Add missing ST4 flags (#188)

This commit adds ST4 specific flags. For compatibility reasons, those which
are not available globally in ST4107 are initialized with numeric values.

Note: flags module is obsolete as of ST4132. Plugins targeting builds after,
      should directly use sublime API classes.
