we now save and restore some variables in tabbed chat window (gpg_enabled) when we split / merge windows

idem for gc window

*by* *default* without any ways to unclobbered options since the rest of the
code is *NOT* working. *donkey*.

begining is in the previous commit (sorry)

redoing my cleanup. the print are now ALL commented. they were left just in case Vincent wanted to test easier. Gajim would run after my cleanup, and even advanced config would run. As yann has said in the past, svn is a place of DEVELOPMENT. Please Vincent just because of 3 prints that were not commented out IN ORDER TO HELP YOU if you went to hack, you should NOT revert all the fixes. Yann said this is strong I would say sth worse.
-- edited by tab. this is not the place for laundry.

only half of the diff is correct (the window opening).

lots of lines looks like nk's experimentations and obviously do not cleanup
anything nor make the thing works:

* print 'show', name
* self.filterstr = 'account'
* print 'refilter starts'
* print self.filterstr
* self.modelfilter.refilter() #FIXME: does not work!

advanced config allow opening only once, cleanup in filter [still does not work], cleanup in glade for advanced config window

when we right click on a contact that is not in the roster, there is 'add to roster' in the menu (fix ticket #55)

it can be configured through the advanced config window
fix ticket #184
