Audex 27.04 - Upcoming major update and early translation availability

Oh, I see, thank you for the catch...

So, I do need to extract:

1. tr() strings
2. QCoreApplication::translate() incl. Qt disambiguation contexts

and fix the Messages.sh accordingly. Furthermore I'll create a regression test 
to verify that the strings actually appear in the generated POT file.

One more word to the new CLI of Audex: The CLI is intentionally english-only. 
It does not load translation catalogs and always uses the original english 
messages provided by the engine.
To make that sure, I think something line "! -path './cli/*'`" should be part 
of the message extraction in Message.sh.

Reagrds,
