Indentation support for the ANTLR parser (as discussed in #192) (#194)

Indentation support for the ANTLR parser
    - some clean-up of the parser code (TODO: file input could be improved, more clean-up)
    - get rid of Translator and specify all syntactic rules in antlr4 grammer
    - support for else-when shorthand in the grammar
    - rename Begin to Block which makes more sense
