Subject: Define flags in CMAKE_C(XX)_FLAGS are now included in SublimeClang
 settings.

Changed the the SublimeText2 generator name to Sublime Text 2.

Fixed a minor issue where if the build directory was outside of the source
directory an unnecessary folder_exclude_pattern was generated in the
Sublime Text 2 project file.
