Investigate if hover is hiding actions on mobile devices

[Igor Santos]

There are some actions (such as the heart icon on user/event lists?) that are hidden until the user hovers the item. This is easy on the computer, but there's a piece of JS (beginning of theme.js) that adds .hover class to "correct view on mobile devices". We should see if that behaviour really works and makes for a great UX; if not, the hover actions should be removed and hover would only be used for eye-candy.
