[FIX] name_search() using ilike on field id or any integer field

When looking for an issue number, it's more useful to match the word in
the whole string instead of just a part of it.

The limit on the list of answers and questions posted by
a given forum user is purposely limited to reduce the
performance penalty for displaying them all.
(see 78fa8619)

However seeing the full list is useful for forum moderators
(e.g. when tracking down abuse), and there are only a few
such users with high karma, so enabling it for them is
negligible performance-wise.

Fixes #3955

* remove ZeroClipboard, pain to test locally and deployment didn't work
  right due to needing absolute path to the swf always
* remove the clipboard alteration on the fly, behaves oddly and can be
  confusing
* add an explicit button to expand and collapse the setup content
* fixup some styling

use search_count instead of search

When a pos.session is launched, all the products are loaded. If the product
was deleted in the backend, it was still possible to sell it in the pos.

To allow overwrite in submodules and more readable code.

The first line having the globalisation code is the globalized amount,
then the next line having this same globalisation code
is the last line of the globalisation (the last children).

The first line must no be included in the bank statement,
but the last line must (as this is a real children line)

This is a regression of commit: cbc52f80

Official doc concerning globalization code:
The value which is mentioned (1 to 9), specifies the hierarchy level of the
globalisation of which this record is the first.
The same code will be repeated at the end of the globalisation

pyeval.  This will be useful for adding better filters (such as this
week) in the searchview.

Seems like the wizard was still looking for the old js context hack from before d5a89059 instead of testing against the new field

- delete a forgotten print
- allow pg_dump custom dumps to be larger than the available disk size, the
  previous commit allowed dumps to be larger than memory, this one remove this
  limitation. zip dumps are still limited to by the disk size.

- let the user choose between the pg_dump custom format or the zip format including the filestore
- use file objects to allow dumps larger than memory
- postgres subprocess invocation is now clean and thread-safe, we dont touch the local process environ anymore
- add a manifest to the zip dump format with version information about odoo, postgres (pg_dump doesnt output it) and modules

As entering a wrong value in the grouping field of res.lang,
for instance '[,]', leads to an unavailability of the web interface,
We add a constraint to prevent entering wrong values.

If a survey has "allow users to go back" option enabled, users can go back to previous pages and change their answers before submitting the whole survey.

This commit fixes the very special case, when the user reaches the last page of the survey, then click on "Previous" button, then reopen the survey from the invitation URL (/survey/fill/<survey_id>/<token> without the /prev flag in the URL). This won't crash anymore.

This commit fixes #2658 and #2680.

When user answers to multiple suggestion questions with a comment box,
the comment box was prefilled with the ID's of the suggestion instead of
user-entered data.

This commit fixes #3149 and closes #3171.

Avoid creation of doublon survey_user_input entries when a user loads the landing page of a survey (/survey/start/... route).

Due to some strange spec, jQuery.ajax() function called with "undefined" URL will do an extra call to the URL of the webpage where the script lies (http://api.jquery.com/jQuery.ajax/). Now, we check that URL is not "undefined" to avoid those calls.

By the way, this problem probably happened in every page that had survey.js in its assets... (correct loading of survey.js is fixed in saas-6 at 4dd5dbb2, this fix is complementary.)

This commit fixes #3032 and closes #3337 #3338 #3092.

The first term of a po file is a comment for translator e.g.:
msgid ""
msgstr ""
"Project-Id-Version: openobject-addons\n"
...

This comment is ignored if there is no source and it is the first term of the po
file. The first flage was disabled too late and if the following terms also
started with an empty source (for too long terms), they were skipped as well.

Disable the flag as soon as the condition is evaluated to make sure no
additional terms are ignored. opw 619786

[FIX] Purchase: replace SQL by ORM because ORM replace date=False by date is null automatically. Fix #4691

Payment info such as "You will be redirected to..." should be translatable.

When url_for was looking for a route which match, it was only looking for GET route.
So routes which were restricted to be used only with a POST method, were never found.

The result was that urls in website for route post (form in most cases) was never prefixed with the lang.
So the request.lang was always the default lang from website...

If you was creating a sale order (in ecommerce), the lang used in sale order was wrong and the description not in the current lang.
