Event CTA buttons don't line up on tablets properly

[mattstratton]

Expected behavior

Register, Propose, and Follow buttons should line up nicely when they stack

Actual behavior

They don't, at least not on a tablet size.

Reproduction Steps

Look at an event the resolution of a tablet.

This one is going to be kind of annoying. I think I know what is happening; it's just wrapping, but those buttons have margins on them, which it is implementing.

It might make more sense to have the CTA div be a little wider on that size.

OK, so I think that this can be better solved by putting the whole CTA block into some nicer <div> stuff with bootstrap, rather than just having the elements wrap themselves.
