#10 Default error page/Page Title

[Anonymous]

Error page are not fully implemented right now. With
some page displaying only "false". To handle error in
client-applications, it'd be more consistent to
retreive an error page (which could contain the error
explication, but this I don't mind right now) with a
SINGLE FIXED ERROR TITLE.
At least i'd like every page to have a definitive title
(some page don't even have a title), so any client app
can easily know what page was received from the server.
