Refactored lang::qls::analysis::Messages

And more refactoring.
Refactoring again.

Fixed imports of extended modules in ast::Keyword

Strangely enough, this only results in errors when running the unit
tests a second time after changing something in those Keyword modules.
Apperently, the modules are otherwise cached.
Extracted getKeywords from lang::rascal::grammar::definition::Keywords (more)

It seems unintended to import that module, as it is part of the Rascal
parser. Also, importing it is dead slow for some reason; this is way
faster.
Whoopsie
Hmm, can't seem to replicate the bug with a minimal testcase. Weird. Any clues Jimi?
