SublimeText 2 Gen: Set the sublimeclang_options_script property.

The sublimeclang_options_script property is now set in the project
file. It is set to execute a python script that reads the JSON options
file to get options per source file. Python must be installed and in the
path for this feature to work from Sublime Text.
