Added model-level settings
Added development dependencies
Added #settings= to set settings for object that has_settings in bulk
Test #teardown should delete all users
make #all return defaults as well
Updated README to reflect that #all also includes default settings
Update test for #settings= to clarify that it does not replace all settings and that it overwrites existing settings
Added caching and tests
Caching made compatible with Rails 2 (by copying code from Rails 3)
Temporary disabled support for Rails 3.0.x and Rails 3.1.x
Test with Rails 3.1.x
Bump to 1.1.0
Merge remote-tracking branch 'jimryan/master'

Conflicts:
	lib/rails-settings/settings.rb
Fixed tests
Some test housekeeping
Readme: Added description for model-level defaults
Bump 1.2.0
Added test for issue #18
Removed caching, because it does not work with associations
Don't require a removed file
