Change database name to be more Trasto-specific
Add Pry as development dependency
Expect hstore keys to be strings, not symbols

I think this is due to the hstore implementation
being used in Activerecord 4 rather than the gem.

This fixes many bugs with AR4.
Remove I18n.enforce_available_locales warning
Add Appraisal gem, set up for Travis
Ignore all gemfile locks
Use PG on Travis
Test on indifferent access hash, because of gem on AR3

AR3+gem: hash with symbol keys
AR4: hash with string keys
Write translation hash with indifferent access, for same reasons
Fix "keys" exception on blank record
Don't require hstore gem in AR4
Remove hstore gem dependency for Rails 4, push to user
Correct Readme gem

[ci skip]
Fix rubocop offenses
Convert specs to RSpec 3.0.3 syntax

This conversion is done by Transpec 2.3.6 with the following command:
    transpec

* 14 conversions
    from: obj.should
      to: expect(obj).to

* 7 conversions
    from: == expected
      to: eq(expected)

* 3 conversions
    from: obj.should_not
      to: expect(obj).not_to
