[IMP] add an easier to use XML-RPC faultCode compliant protocol
remove the /openerp/* routes, they were never used because the protocol was too 
different from the historical /xmlrpc/ routes. Instead we introduce a
/xmlrpc/2/ route identical to /xmlrpc/ with the only difference that it returns
int faultCodes making it compliant with the XML-RPC specification.
[IMP] ir_actions cleanups.
Remove deprecated old style wizards.
Remove unsed get_model() function.
Move crons into Actions menuitem.
Move todos into Actions menuitem.
Merge branch 'master' of bzr::lp:openobject-server
