Log Message:
-----------
Added possibility to hide empty text entry line for chat windows

This can save some of the precious screen space when working
with low resolution (640x480 is the minimally supported screen
resolution at the moment). Also it may be handly when user input
is not needed (a window with some informational text messages).
