Edits to .sublime-project settings require sublime text restart

Repro steps:

1. Create project that relies on non-default include paths
2. Install plugin
3. Edit project file, and add your non-default include path to cc_include_options. Save your changes
4. Edit and save one of the files in your project

Expected:
The new include paths are picked up as soon as they are saved to the config, and you get no errors from Clang-Complete

Actual:
The include path is not picked up. Lots of "file not found" errors, complaining about your header files.

The work-around is to fully quit sublime text (not just close your project), and open it again. Things start working well at that point.

I think if this problem was solved that a bunch of the other issue reports would go away.
