	   Rambetter on Sat Nov 13, 2010:

	   The following line fixes parsing and writing of floating point numbers in locales such as
	   Italy, Germany, and others outside of en_US.  In particular, in such problem locales, users
	   are not able to use certain map entities such as "light" because the definitions of these entities
	   in the entity definition files contain floating point values written in the standard "C" format
	   (containing a dot instead of, for example, a comma).  The call sscanf() is all over the code,
	   including parsing entity definition files and reading Radiant preferences.  sscanf() is sensitive
	   to locale (in particular when reading floating point numbers).

	   The line below is the minimalistic way to address only this particular problem - the parsing
	   and writing of floating point values.  There may be other yet-undiscovered bugs related to
	   locale still lingering in the code.  When such bugs are discovered, they should be addressed by
	   setting more than just "LC_NUMERIC=C" (for example LC_CTYPE for regular expression matching)
	   or by fixing the problem in the actual code instead of fiddling with LC_* variables.

	   Another way to fix the floating point format problem is to locate all calls such as *scanf()
	   and *printf() in the code and replace them with other functions.  However, we're also using
	   external libraries such as libxml and [maybe?] they use locale to parse their numeric values.
	   I'm just saying, it may get ugly if we try to fix the problem without setting LC_NUMERIC.

	   Usage of sscanf() throughout the code looks like so:
	    sscanf(str, "%f %f %f", &val1, &val2, &val3);
	   Code like this exists in many files, here are 4 examples:
	    tools/quake3/q3map2/light.c
	    tools/quake3/q3map2/model.c
	    radiant/preferences.cpp
	    plugins/entity/miscmodel.cpp

	   Also affected are printf() calls when using formats that contain "%f".

	   I did some research and putenv() seems to be the best choice for being cross-platform.  It
	   used to be a function in Windows (now deprecated):
	    http://msdn.microsoft.com/en-us/library/ms235321(VS.80).aspx
	   And of course it's defined in UNIX.

	   One more thing.  the gtk_init() call below modifies all of the locale settings.  In fact if it
	   weren't for gtk_init(), we wouldn't have to set LC_NUMERIC (parsing of floating points with
	   a dot works just fine before the gtk_init() call on a sample Linux system).  If we were to
	   just setlocale() here, it would get clobbered by gtk_init().  So instead of using setlocale()
	   _after_ gtk_init(), I chose to fix this problem via environment variable.  I think it's cleaner
	   that way.
