+ Extended RubyParserStuff#new_case to take line number.
+ Removed RubyLexer #extra_lines_added. No longer used. Complex heredoc lineno's possible screwed up.
- Fixed line numbers for odd cases with trailing whitespace. (presidentbeef)
+ Turned off oedipus_lex's automatic line counting. (pushing to oedipus_lex soon).
Cleaned up some line number tests
