Xchat Backend advance

[Wade Mealing <wmealing subverted net>]

After some minor updates, and some words of wisdom from Jimmy and Nat, I
have done a few minor updates to the xchat backend.  Please let me
(wmealing subverted net) know how this goes, you will need to have
sql-lite installed as per the installation documentation.
