Adding formtastic-bootstrap stylesheets.
Changing the looks of the seatmap.

The seatmap is now contained in a box with rounded corners and each tile is
divided by a 1px solid border. I think this look is more pleasing.
Seatmap is only shown if one has tickets to seat.

The lack of this helper caused an error due to #events_path not being defined
anywhere.

Only show link to seat map if it's enabled.
Adding error handling of ajax features.
Cleaning up bootstrap overrides.

Seeding of several ticket types and a larger map.
More sane explanation for no ticket reservation.
