Fix: Corrected type of size in GuardBytes to be size_t, not int.

Updates to make Fixture more useful (thanks malsyned! It's nice that someone is helping out with the Fixtures extension!)

Thanks, Bryan.  It's nice to have better documentation (Int config options, in this case)

I love it when things are made clean! Bryan A Jones smooths out some wrinkles in WIDTH detection.

     Document failing approach (sizeof).

Update tests on +/- infinity to work with MSVC++ 2008

     - Change type of floating-point constants to single/double precision
       as appropriate.

Nice work, Bryan... thanks for the cleanup!

     For doubles, make sure all constants are double-precision.

Improved support for special floating point values

UnityAssertFloatsWithin now fails any test where either a NaN or Infinite value is passed as expected or actual.

Fix For Issue #10 - Thanks Ross.  Nice simple solution.

Pull request.

Fix issue #7 INTx_WITHIN_MESSAGE() macro

The reason that TEST_ASSERT_xyz_WITHIN_MESSAGE() family of functions
doesn't print any message is because is calling a re-use macro from the
TEST_ASSERT_xyz_WITHIN() family of functions. Due this two functions in
unity.h calls the same function from unity_internals.h, the message is
nullified at this point. The issue is fix by passing _message_ arg to
the 4th argument of *UnityAssertNumbersWithin()* function.

Conflicts:
	src/unity_internals.h

Added directory task to create temp build/ folder, and added .gitignore to prevent this new folder form being tracked by git.
