Version of SqlSessionStore for Rails 2.3

If you're using SqlSessionStore (originally from Stefan Kaes of
railsexpress.de) and upgrade to Rails 2.3, it will break.

I have a github version that I have updated for Rails 2.3, and also
added a new "native columns" feature to. It is available here:
http://github.com/nateware/sql_session_store/tree/master

It is backwards-compatible with Rails 2.2 and earlier, so you should
be able to update your application (probably worth backing up the old
one just in case).
