Remove jQuery

Here's a first pass at removing jQuery from Uchiwa. Tests are currently failing & I haven't replaced toastr yet but bootstrap tooltips are working. This is still in-progress.

@palourde I removed the bootstrapTooltip directive with the directives provided by the angular-ui bootstrap project. It doesn't seem to use the title attribute for the tooltip value, but instead uses tooltip="value". I've removed the title attribute for now but I can re-add it if it should be there for accessibility purposes.
What do you think of using the $cookieStore module (https://docs.angularjs.org/api/ngCookies/service/$cookieStore)?

It's already used to determine the site theme: https://github.com/sensu/uchiwa/blob/master/public/js/directives.js#L14

Otherwise, angular-toastr does not parse HTML so I have this happening: http://i.imgur.com/JkzviND.png. It seems we have to pass the title as a second argument so ignore this issue, I will simply remove the 'strong' tags in the backend!
