Bugfix #2704

Modified bFTGL so the bitmaps supplied by the font itself aren't used.
Patch originally supplied by Shizu, somehow this was never added to
FTGL.

Be sure to build binaries with bFTGL, not the provided ftgl.lib from the
lib dir. (this one can be deleted afaic)

Uncommitted my last commit.

Added console printout when rendering in parts, to keep track of progress.
Requested by Relic.

Teeth's msvc6 projectfiles commit solved almost all my bf compile probs, only one problem remained;
the including of <MT_assert.h> in the NG_network project. So here's a fix.

Removed a couple of redundant "FTF_api.h" includes,
removed leftovers from Freeimage/Imagemagick experiments
and removed stuff from a Quicktime for linux implementation.

Also removed the (win32) Fullscreen button from the UI and
disabled the corresponding commandline option. The code is
still present to reenable the option whenever the ATI issues
get solved.

Bugfix #2228

Quicktime on OSX now saves Movies with a correct alpha layer.
Also fixed the bottom-to-top orientation problem which occured
with several (OSX) applications.

Fix for mipmap userpref button. (it was using the wrong userpref value).

Modified interface texture font support, which should work nicely with the freshly added bFTGL library.
Also removed some redundant #include's on some files.

Modified FTGL for proper texturefont support.
Also fixed msvc6 (release only) projectfile to build and output correctly.

Added experimental option to use GL textured interface fonts.
Set preferred method in userprefs->language & font.
Kinda requested by Kaito, i'm sure he regrets after seeing
my code changes.

This commit includes a patch provided by Jacques Baurain,
which seemed nescessary to handle font sizing properly.
Thank you !
