Session handling busted on Oracle

[Jonas Pfenniger]

Hi Daniel,

I think that I have corrected that last week changeset [226]. The
problem was that Session uses it's own kind of id (hashid) and that by
default, ActiveRecord uses an incremental version.

See : http://code.whytheluckystiff.net/camping/changeset/226

Please tell me if I introduced any regression.
