Rails 5.1

[glaszig]

this adds tests for rails 5.1.

unfortunately, controller testing changed quite heavily (they're integration tests by default) so those won't run on anything < 5 anymore. not sure how you'd like to approach this.

also makes some other adjustments for which i was too impatient to create separate PRs:

• only install growl if running on macOS
• gitignore gemfiles/*.lock
• add test-unit gem to rails 3.2 gemfile because it got removed from core ruby since 2.2+
• updated schema dump (mainly ruby syntax)
• code climate integration according to 1.0 docs
• made config class compatible with older rails versions (currently only works with active support 4)
• upgraded rspec-rails because of changes in newer rake versions
• remove version-lock from acts-as-taggable-on

[glaszig]

alright. 4.2 and 5.1 tests are green. supporting earlier versions is pointless pain, in my opinion, as they're all eol.

@Bodacious, still there?

@glaszig Thanks for doing this. I'll get back to you ASAP with these PRs.
