keep active window after system save
The Meridian 59 client has *always* reset to the same client side group
(spell list) after a system save. This was very annoying during PVP and in
general (e.g. to use equipment you would have to use the mouse to reselect
the inventory window)! This update persists the most recently selected
client group through systems saves and also client logins. This client
side operation has annoyed me for a long time and I hope you will agree
that this is an important and useful fix! Implementation wise I have
mirrored how the existing GetPlayerInfo method is shared between the
meridian client and main library. This update includes a small client
version revision and some helpful debugging information.
