Bugfix and improve debug mode

[GorogPeter]

• print parse errors before abort

• print interpreter error before abort if debug mode set

• print error at lexer initialization fail

• print "assert failed" instead of just abort

• make printing data fancier in debug mode

• remove dump() in ByteCode and replace it with getName() and printExtra()

• fix 2 typo

• bugfix at table access

Old debug mode:

[GorogPeter]

I closed this pull request to separate the two main improvements (improving debug mode and printing error messages). Soon I'll make 2 separate pull request for each improvements. Sorry for the overcomplicating.

Ok thanks!
