Merge pull request #23 from javacruft/master

Fixup use of argparse for python3.3
Use codecs package and context manager for reading

open(..., encoding=...) is only available with py3k, but the codecs
package is around forever. This way we always end up with a unicode
object holding the contents of either README.rst or LICENSE. Use a
context manager (with keyword) for extra clean file descriptor closing.
Fix setup.py PEP-8 issues (and catch with tox)
Support semicolons in mixin arguments

Include parse with debug flag

When "-g" is specified on the commandline, not only the lexer should be
run in debug mode but also the parser.
