Cleanup and DB Script

Hey, I made some changes which you can merge in if you want. I did:

1. created an SQL script that regenerates the database (drops the old table, runs CREATE TABLE again,    and adds some data).

2. removed a bunch of files that git was still tracking from before we added the .gitignore file. Most of the files were temporary ones generated by the build process, and really shouldn't be uploaded to version control. It was kind of my fault, since I forgot to add the gitignore file before our first commit.

You should be able to merge these changes into the master branch with one click. I've actually never created or merged in a pull request before, so I'm not sure what the process is. :)
