Merge pull request #147 from alanedwardes/vbsp-fixes

Changed VBSP to check both the EXECUTABLE_PATH and the MOD path for FDG files.
Fix some accidental new-line stomping.
Specify clobbered registers in POSIX SSE functions

We weren't specifying clobbered registers for our SSE implementations of
VectorNormalize and InvRSquared. Supposedly GCC and clang does not inspect the
assembly to figure out which registers are getting clobbered, so this could
potentially fix some bugs.

This fixes GH-195.
Line-ending fixes for most of the remaining files.

Fixes line-endings for files with extensions vcd, cc, txt, bat, fxc, inc, lst,
proto, mak, mm, cfg, res, rc, def, vmt, vsh, vbsp, inl, asm, m4, vcproj,
vcxproj, sln, in, java, la, manifest, am, and rad.

Also fixes README, CONTRIBUTING, CONTRIBUTORS, LICENSE, CHANGES, COPYING, and
gitignore.

Finally, fixes executable bits.
Make libSDL2.so/dylib into symlinks.
