urlHandler : manage anchors

[bricet]

It would be cool if an urlHandler could manage anchors.

A patch is needed for create() because if create delParam() some params but not all of them, we can not just append the anchor to pathInfo : trailing params will then be appended to the anchor, which is not what we want.

A patch would be may be welcome for parse() just to ease things (even if this should be rarely used, though) ...

Why not supporting anchor into the create() method. But it is useless for parse(): the anchor is never sent to the server.
