Since the GUI2 titlescreen took over, the path to tips.cfg is not
hard-coded in the engine anymore; in fact, this commit also updates that
path, which is in data/gui/default.cfg.
When a widget has both a tooltip and helptip a small text to notify
the user about it. This also means when there is a helptip the tooltip
needs to have a text.
A repeating button is button when pressed down will execute an action,
if the user keeps it pressed down for a longer time it will repeat
this action until released.
The main place where the widget was missed is the MP lobby, I haven't
tested it there much since the lobby is still to slow. This means once
the lobby is fast enough it needs more tuning.
The widget hasn't been wired in the scrollbars, which will be done in
the next commit.
In the macros directory some more generic macros will be defined, the
_initial.cfg should be loaded first. The engine doesn't enforce that yet but
probably esr will add that feature. (The odds of it not being loaded first is
probably theoretical.)
