[FIX] website_sale_options: enable tour test; close and return error log without throw error.

[IMP] crm, gamification, hr_recruitment, project, sales_team, stock: light kanban view harmonization.

Main changes :
- slight harmonization: bold centered titles, aliases display if left and right parts defined
- remove ".oe.e .oe_alias" classes + use of old icons; use fontawesome instead in the various kanban view
- regenerated the css for job position (weird indentation issues)

The goal is to ensure that HTTP requests
done while reloading the client (e.g. the
menu bar, etc.) do not use a deprecated
session context.

Also undo the previous fix from a0ee2b5a
as it would cause other issues (e.g.
prevent setting the admin password/lang
when creating a new db using the db manager)
This logic does not belong in the business
methods of res.users.

[IMP] point_of_sale: load assets with templating sytem so that scripts are not minified in debug mode

[IMP]kanban View: harmonize kanban view by changing head as bold and centered and aliases as centered

[FIX] website: customize menu stay empty if it's open to quick. Don't throw an exception when the tour have an error: log error and close tour.

[IMP] crm (sales_team), hr_recruitment, project: fixed display of alias on kanban view. The alias is not shown when not having alias_name (left part) or alias_domain (right part) defined. Indeed only using alias_id.value is not correct, as we could have '<alias_name>' or 'Inactive Alias', depending on the missing part.

[IMP] join stdout and stderr in error report when sass returncode>0

Master allow translate on noedit sle

[FIX] correct context resetting when changing user lang

if mail module is installed it could be a client action

[ADD] SASS support in bundles

Sass installation:

      $ sudo gem install sass compass bootstrap-sass

If the following error is encountered:
      'ERROR: Cannot load compass.'
Use this:
      $ sudo gem install compass --pre

Removed 'modules' item in ir.ui.view rendering context.
Replaced by lazy helper get_modules_order
