Weird unicode character in ngPopover.js: Â

I noticed that the `ngPopover.js` in your repository have some random unicode character `Â` inside them, which would throw errors should it is included in webpages.

This is one of the line that have it:

```
if (target.attr('ng-popover') ||Â target.parents(['ng-popover'])){
    fadeOutTime = 0;
}
```

Can you have a look at it?
