make hover menus a skin option

[ghost]

I like this skin, but I don't really like hovering menus. I would prefer to be able to click on them. Foundation seems to have support for this by adding data-options="is_hover: false/true" to the topbar and other menus (e.g. page actions menu). There are just two issues I see right now:

1. For some reason this commit adds custom JS to handle hovering the page actions menu. If I remove it and try to use the data-options attribute with hover set to true, the page actions menu becomes a toggle hover instead of of a normal hover. That is, I hover my mouse once to activate the menu, move the mouse elsewhere, then hover again to deactivate it. I'm not sure how to fix this, since I'm not much of a web developer
2. There seems to be a bug with is_hover: false where clicking the button activates the link (appends # to the URL and activates and deactivates the menu near-instantly). This is probably a Foundation issue.

If everything was click-accessible as opposed to hover that would make mobile taps and desktop clicks move congruent too. I like this idea.

Hmm.. this could be handled as another Foreground option.
