Removed the long header strings above the title/scene choosers, they most
likely would not fit in all translations. As a result of this, the scenes
column can be compressed down, leaving more room for window titles.
Obsolete strings removed from en.txt.
Contains two fixes by HomeWorld: A tooltip when hovering over too long
titles in the list control, and the placeholder text over the window
title/scene combo boxes.
