- Userscript encapsulation + clean jshint

[mimaison]

• Added .meta file for future updates

Hi, not sure what your change is about?

[mimaison]

Sorry I should have added more details as it looks like a big change. In fact it's not as big as it looks. I've done 3 things:

• I've added a .meta file and the updateURL and downloadURL tags in the header, so the script can update itself if/when new versions come
• I've refactored the code so it's properly encapsulated within a closure. If you're not familiar with this pattern have a look at Douglas Crockford'c classes
• I've fixed a couple of warnings jshint (a javascript static analyzer) spotted

In the end, it's mostly style. I leave it up to you to decide if you want to merge it. There's nothing wrong with the script per se, I just want to improve it a bit.

@mimaison : Ok, but why did you encapsulated the code? This is is not necessary since the browser already does it when installing.

You also forgot to remove a dead function.

Thanks for the idea of improving Javascript. @ytrezq is right, no need for encapsulation here.

I removed the dead function and fixed some obvious JS issues!

Thanks guys.
