automatically configure wit & wwt about qtwitgui

[GoogleCodeExporter]

im reluctant to include this patch.  i like the idea.  but there are a few 
things the patch seems that it would break.

first, it is linux only.  it could be fixed with a #ifdef.  im not sure of the 
wit default install location for mac.  and im not sure if there even is a 
install location for windows.

second, and more importantly, your patch completely ignores any user applied 
setting.  every time the program is started, it will check if "/usr/.../wit" 
exists.  and if it does, it will use it.  even if the user specifies a 
different location in the settings, next time the program starts, their setting 
will be reset back to "/usr/.../wit".  

i like to specify different paths for wit especially when wiimms comes out with 
a new version or when testing for bugs.  several times in teh past, a new 
version of wit comes out with different text formatting and breaks this 
program.  and many times i see something that does seem quite right in wit, so 
i build it with debug flags or with a bunch of added printf() to track 
something down.  your patch seems that it would destroy both of those. :(

if you can fix these things then i will add your patch.
