updated .gitignore
removed debug output and added capitalization of first word
wrote ShakespeareParser for sonnets
added optional **kwargs to Parser.source()
Wrote base structure for play parser
changed ShakespearParser to use format from other site

http://sydney.edu.au/engineering/it/~matty/Shakespeare/
Advantage over Project Gutenberg: actually one unified format
instead of a bunch of slightly different formats no-one seems
to care about
added _is_next_character and _is_text helper functions
can now parse shakespeare pieces, yay
Merge branch 'shakespeare' into develop
