Vala: Replace current implementation of vala-pack for IdeIndenter and IdeIndexer
As for #1074 (closed) in order to replace current Vala-pack plugin, a new version in Python should be implemented. So there are two ways to go:
- Keep current Vala version and re-use it in Python plugin. A GObject Introspection GIR and Typelib is required, so the Python version can use it.
- Create a replacement in Python. Issue #1097 (closed) is stopping its development and fixing.
