Changes to HIC for support of ActionGroups

Expects that libHeaven will create an ActionGroup object in similar ways
other objects are created. This might be a bad idea given the inherent
nature of action groups.
Emit ActionGroup init code
Add ActionGroup wrapper object
Insert QActionGroup to be found later
Allow to directly emerge ActionGroup objects
Merge pull request #15 from macgitver/feature/agroups

Feature: Action Groups
