src ordnung an java-standad angepasst (-> eclipse-vertraeglichkeit)
extended abstract syntax and variables with the possibility of qualified variable identifiers, which may reference modules... (does not yet affect the translation, hopefully)
Einige Vars zu VarFirstClass gemacht...
finally got the unit tests to compile again... (but some of the tests fail!)
cleanup in Lexic and subsequent changes
rewrote parboiled parser operator parsing; broke negation operator
fixed some things test complained about
qualified vars, cons and types. untested
added JSON serializer

the JSON serializer is not yet implemented completely
many stubs have yet to be implemented
completed simple JSON implementation

unit tests and verification still nyi
doesn't (de)serialize imports
works on old absy (so no qualified ide support yet)
fixed most of the unit tests (except for the unary minus related ones). there seems to be a bug with the letrecsplitter.
played around with letrecsplitter. im quite sure that the tests complain with no good reason.
tried to get rid of pre-defined constructors by defining a special prelude. (to be replaced by module system) but at the moment, the typechecking wonts wok.
implemented signature matcher

also added tests for the signature tester (yo dawg!)
import statement added to parboiled parser; still buggy
Merge branch 'parser' of https://github.com/SL2Team/sl2 into parser
tests were fixed externally by benkeks, while I didn't push my changes
import directives are now being parsed successfully
changed int and real token definition to accept negative numbers (Parboiled only)
removed parser tests that expect unary minus to work (except as part of a numeric token)
Merge remote-tracking branch 'origin/parser' into module_serializer
