msg textview in tabbedchat window problems
for the msg textview [not conversation] either we add idle_add() and make it scroll to then end
just try to copy paste a huge text. it will not scroll to the end [when scrollbar appears]
or we go the Gossip way. Which has one line [we can also stick with 3] but when more lines are needed the give those lines, so the text the user is typing and he's ready to send is always visible, without him wanting to maximize or resize to see what he's typing.
I favor the second way which is better demonstrated if one uses Gossip and tries to copy paste a huge text in there.
the second way also fixes the annoying gtk+ bug described above, or else we do the idle_add() workaround
this must be in 0.8
