new connection and GnuPG class

minimum width in gc window for the contact list on the left

client info and os info on 2 lines instead of one in vcard_information_windows

code to take into account the do_not_send_os_info option (need gajim restart to be tacken into account, will be fixed when threads will be removed)

fixes for when disabling emoticons in prefs [gajim did not boot], add_remove_emoticons_window and class, better popups [needs more attention {me is on it}], no more emoticons tab, introducing version.py, hide os information included, and fixes allover.

change the bg color instead of the fg color when a contact (dis)connects. Colors have to be improved

show newly connected contacts in green and contacts that have just disconnected in red before removing them. Presentation/colors have to be improved, but the principle is there (to be tested).

now when we do make, it compiles py files to pyo and make install install pyo files instead of py files

do show_all implicitly everywhere [glade windows visible=False]. I did this so when show_all() it will be shown then [after connect and stuff], and not when being parsed
