update path to some files so they match the new structure [it is far from complete and of course it is vital to have the paths fixed before 0.7]

gajim.sh --> gajim.py, adding psyco support if available, small fix in new message dialog if @ is not given

ImageCellRenderer has now better name, gajim.py --> gajim.sh [needs fix to makefile to make it work, padding and xalign trying to clean up (don't work yet). added a fixme in new message dialog about focus problems..
