Initial support for TTCN-3 v4.1.1

Initial parsing and editing support for TTCN-3  v4.1.1  Core Language is available. Formatting, metrics, and refactorings are pending adaptation. It may still have a few rough edges so be patient and help us iron them out by reporting issues.

In addition a few small issues were fixed, such as the incorrect symbol assignment to module parameters of the same type declared on a single line using comma notation.
