Expand integration test suite

[orenyk]

#416 added integration tests for many basic reservation actions, but we should also test out the less common app actions:

• Announcements (2015-11-09: partially done, dismissing an issue Cannot dismiss announcements if not superuser #1339 and probably not testable, we should add specs for adding / editing announcements)
• Blackouts
• Equipment handling (incl. deactivation)
  • Creating / managing categories
  • Creating / managing equipment models (2015-11-09: only basic view specs, split into two files for no reason)
  • Creating / managing equipment items
• Reservations index view
• Reservation handling
  • Editing
  • Archiving
  • Request approval (check that the correct e-mail is sent when reservation starts today)
• User handling
• App config setting
• Checkin / checkout procedures
• Requirements
• Reports

I feel like some of this has already been done, I'll run through our integration specs now and see what the situation is.

EDIT I guess I was ahead of myself when I created this issue, most of it has not been completed 😞
