Fixed typo in pom
Bumped up project version to 2.8

We'll move to 3.0 once we get more of the new stuff running :-)
Merge branch 'version3' of github.com:bedatadriven/activityinfo into release
Revised api2 model classes

UserForm -> FormClass
FormInstance,UserFormInstance -> FormInstance
Cuids are used in place of Iris when identifying user-created objects.
We still use Iris for subclass/superclasses as they may refer not to user-created
content but external definitions.
