Add SQLite support and refactor database

I basically redid the whole repository.  Sorry!
- Refactors Database to be more of an abstract class.
- Add's SQLite support.
- Fixes some bugs in your MySQL support.
- Adds JavaDocs (Yay!)
- Adds a .gitignore
- Removes /bin
- Adds a README

Hopefully you enjoy! I'll be using this in my newest project.  Maybe at some point you can get it on Maven?
