[FIX] _handle_exception() logic amongst requests and ir_http objects

Changes in website's ir_http#_handle_exception():

- exception is mandatory, can't be None anymore
- we don't touch non website_enabled requests
- we don't touch explicits plain responses from parent
- logic flow is now easier to read (I hope so)

Change in website's ir_http#_dispatch():

- In case of real 404, instead of returning self._handle_exception(),
  just let parent do the job (so we call super())
[FIX] check after openerp's AccessErrors in website's _handle_exception
[FIX] Sitemap - Back forward from saas-5 5cc1317a5f4525e8748692c69c3854773cf95454 to have the url_root in sitemap
[FIX] Forum / Sitemap - Restrcit the domain from controller, else the sitemap fetch response without the question
[FIX] Forum - Redirect permanently to the question, if post_id in url is not an answer.
[FIX] base_action_rule: more flexible wrapper signature

Some objects (e.g. account.move.line) have a different signature than the classical 'cr, uid, ids, vals, context=None' and may add extra arguments.
This fix allows to create rules on these objects and still pass the valid arguments.

Merge pull request #765 from odoo-dev/saas-4-sitemap-forum-jke

[FIX] Forum / site map - redirect to question topic and response bypassed by sitemap
[FIX] http.dispatch: call handle_exception() even w/ session missing/expired

This gives JSONRequests a chance to return
a proper JSON-RPC result when an HTTPException
is raised downstream, instead of returning a
plain HTML 404 error.
