[FIX] website_sale, website_event_sale: updated tests according to the new dom of the checkout page introduced in pull request 232

Before this commit, @mode=primary would be sorta-ignored[0] if the current
view and its parent had the same model: the current view would *still* get
applied (as an extension) when asking OpenERP for its parent. This commit
makes mode=primary views behave regularly, they are *never* applied when
asking for their parent, only when asking for them or their children.

This allows "forking" views, and using extended views in some contexts without
breaking or duplicating the original view

[0] there was actually a problem when asking for the current view directly,
    first its parent would be resolved by applying it, then it would be
    applied to resolve itself, the view would thus get applied twice (oops)

[IMP] website_sale: correctly submit the payment form using a post request, correctly create the tx asynchronously

not sure that's actually useful, and can still go always -> enabled -> disabled...

Also add a few comments to note understanding of code

rco notes that group tests are generally intersections, if the user has *any*
group set on the object he can see/use it. This change is a literal
translation of the original semantics, which may be wrong.

just forwarding the context object does not count as using it, if callees want
a context they can ensure they've got one on their own

[IMP] don't pointlessly recreate view_obj every time _views_get is called, better use of pool & data APIs

should probably validate that there's an inherit_id (?)

Not used yet, only defined its relation to inherit_id:

not inherit_id + primary -> ok
not inherit_id + extension -> error
inherit_id + primary -> ok
inherit_id + extension -> ok

[IMP] Move website assets to frontend bundle

[IMP] payment addons: fixed submit buttons: now have type=submit (and not image or nothing) and removed name, because this may cause issues when trying to submit a form manually with type=submit and a name. Also improved js code in website_sale to correctly handle the click binding, the asynchronous call to the server to create the transaction, and then submit the form. As form submission is synchronous in javascript, we cannot use the deferred. Instead we prevent the click event from bubbling, wait for the server to create the transaction, adn then manually submit the form.

Now: intercept the call, make an asynchronous call to create the tx, then continue to the acquirer. Previous this was done by
a redirection, leading to a get request beign done. However it should be a post request.

[IMP] When no result is displayed in m2o field with option "no_create", add a "No result" value to avoid confusion.

* Deleted: manually translation in es.po
