Refactored CRM_Volunteer_Upgrader->findCreateVolunteerActivityType() to accept arguments and create other activity types.
Bugfix for createActivityType method.
VOL-42: First pass at modeling Volunteer Commendation (both for new installs and upgrades).
Fixed regression in which createActivityType returned OptionValue IDs rather than ActivityType IDs (AKA OptionValue values).
Merge pull request #194 from GinkgoFJG/VOL-42
