fix some problems with drag and drop when we merge accounts

do not use changed signal in disco: when we write some thing this signal is emited each time we add / remove a character, so gajim sends many useless requiest

Plz do not use glade 2.10: pygtk2.6 is really not needed atm, and many people don't have it so we must not depend on pytgk2.6 fot the moment

for my try often means "I don't really know if it will work so I put it in try"

new message dialog fix for title and add to accounts shouldn't list not in the roster. plz see my fixme comment

do not show agents if they are not childs of another agent. It fixs that bug: you ask agents from an account1 and quickly ask agents from another account2, then answer from account1 arrive. They must not be displayed, it's too late.

eugenia colors as default, fix in makeing menus, and better regexp (doesn't detect http://) anymore) [thanks jajcus]

show_all/hide for roster and accounts window, better strings when multiple accounts [has a bug], changelog is better now

expand the first row

service discovery is now asynchronous, we can send and receive other messages while we browse agents (YEAH !)

we can now browse all jabber servers
save the last server discovered

ficking ticket 119. 115 and resizing problems that we had with edit groups dialog (now resizes very nicely)
