RLint is coming

Hi folks,

Finally, I get back to develop RLint, because I'm really excited with RHash amount of download (3777). Besides, I felt a emptiness about a tool could help detect code pattern mistakes. I've seen in Python a software amazing, the Pylint. Furthermore I think I can use this tool in own projects and share with Ruby community.

First features:
- Tabulator check (Space vs Tabs)
- Class/Module name (CamelBack vs Snake)
- If/Unless parenthesis check - Column delimiter
- Class/Module/Method size (Total of line)
- Method parenthesis check That's it.

If someone have a good idea for feature, tell me.
Let's start the ball rolling.
