Events

New version of the event index page.

Cross-browser tests for javascripts:

- Working on Safari and Chrome (webkit based browsers)
- Slower on Firefox, one small features presents a bug (will be corrected when debugging the whole website for other browsers)
- No tests on Opera and IE yet.

I need to slightly modify the event show page before merging to v2. I did the pull request yet 'cause pull requests are cool.
