Preparation for publishing on npm

These changes should help with #180 and #12. 

- I changed the npm and bower version to `0.0.1`. I can change it to `1.0.0` if you like.
- I renamed the module name for npm to `prism-js` since [prism is taken](https://www.npmjs.org/package/prism).

Also:
- Added [JetBrains](http://jetbrains.com) files to the `.gitignore`
