Update rails-bootstrap to correct tooltip behavior
Update delayed_job to remove deprecation warnings
Small layout improvements

Trying to create a standard way to show selected threads/items in lists and
the menus that are shown over them.
Still needs improvements.
More small layout changes, more icons and better colors

Most changes in the users' homes and application navbar.
Thumbnails as default at spaces/index and small layout changes in it

Changing the place where the buttons to select list/thumbnails and the button
to create a new space are placed in this page.
List of activities link in the header of users' homes
Show past 5 activities instead of 3 in users' homes
Crete standard form to report spam for events and posts

For posts it was already ok, but for events wasn't working. Now they use the
same partial to render the form.
The actions to create spam reports were also modified to make more sense.
Better layout for spam icons on posts and events
Simplify icons and links for superuser

The icon inside the avatar is now simpler and the "manage" link in the navbar
is also more like the other links. Trying to make the pages simpler.
Smoother colors in the navbar's background

More like the navbar in the frontpage now.
Merge remote-tracking branch 'origin/updates' into branch-v2

Conflicts:

Also had to update devise and cancan. Rails updated to the latest
version that caused no conflicts with station.
Updated it specially because it solves this issue:

is not being used anywhere, so is not included anymore.
