evil pull request with fixes on the new bank statement reconciliation widget

[MERGE]  http routing: fix handle_exception logic and _authenticate exceptions

* Better separate JsonRequest and HttpRequest handling
for exceptions, so each type of request handles exception

of internal errors:
 - openerp.exceptions.AccessDenied
 - openerp.http.SessionExpiredException
