Add colorSpaceName=sRGB to Textmate themes for proper color matching

I'd always wondered why cross-application themes like Tomorrow Night (or Solarized, or Monokai) didn't look quite right in Textmate 2 vs Terminal/iTerm/vim/Sublime, then discovered today that Textmate now recommends adding a colorSpaceName = sRGB key/value pair to theme files for better color correctness. See https://github.com/textmate/textmate/blob/master/Applications/TextMate/about/Changes.md#2013-02-18-a9383

Attached are screenshots of master (w/o colorspacename setting):

And my pull request (w/colorspacename):
