* fix nameerror on SessionExpired exception not being imported
* remove pointless RequestUID instantiation by single placeholder object
- may be replaceable with a LocalProxy or something along those lines?
* rename default/nodb routing map
* make better use of werkzeug API
* move lazy routing_map instantiation to property in ir_http.find_handler
- do we have some sort of lazy_property?

Split low level dispatching and high level dispatching.
Low level dispatching is used when the db is unknown it's only used by a few
controller in base and web.
High level dispatching is used when the db is known, it is used by most
controllers and it handles authentication and errors. Because it's a regular
osv object all it is fully overridable by openerp modules.
