- Split Main in 2 classes
  - Main the cli client
  - LexGenerator that generates java code
- Replace manual command line parsing by commons-cli
- Replace Options by GeneratorOptions, an immutable object
- Remove all statics from Out
  - Deleted dead DEBUG statements
  - Throws exceptions when possible (which removes a few dependencies on this Out logger)
  - Also simplify error formatting with varaargs
- Update maven-jflex-plugin
- To reduce scope on this XL change:
  - Move anttask in a separate directory. Build broken, even though mostly update. TODO: Make it compile as a POM.
  - Move GUI in a separate directory. Build broken. TODO: Make it compile as a POM.
  - testsuite-maven-plugin build broken. Renamed Main to Tester to avoid confusion with jflex.Main.

I was setting default options, which caused tests with an expected dump to fail

    - show the full path of the expected file
    - output the actual output in a file in case of failure

Throw the scanner exception directly when there is one [rather than wrapping in genrator exception]

Throw the GeneratorExcption directly rather than wrapping it inside a new GeneratorException

Restore log of "Writing code in Emitter ctor"
But do it in LexGenerator, raher than Emitter ctor.
Move Emitter.normalize() to LexGenerator.

Regressions: fix macro-exp2

Out has been renamed log

This is how it was done before.

Fix regressions tests not detecting scanner generation logs, such as "Including [file]"

Fix regressions macro-exp2

There are still some usages of Out
