Subject: Two new encoders: debug and xml.

encoder.rb: new token handling
encoders/statistic.rb: using new handling

ruby_helper.rb: small improvements
ruby.rb:
- escapes in subtoken
- Float detection changed
- some multi-char operators are now scanned as one token
- def and module definition handling changed

bin/coderay: improved, new interface (still in progress)

plugin.rb: more expressive load error message
