Add a StrongParametersMatcher
Add #description method to DelegateMatcher

Also, fixing code style for documentation, and update the method
referencing style to be #method_name instead of :method_name.

Fixes #226
Remove RSpec #should syntax to support Test::Unit

There was no need for us to call `#should` in those matchers, as we only
need to return true/false in `#matches?` method. By removing those
`should`, those two matchers are now working fine with Test::Unit
and minitest.

Modified default attribute error message generation

Generation of the default attribute error message is now delegated to
ActiveModel::Errors where possible, avoiding inconsistencies where
default locale entries have been overridden from the ActiveModel
defaults and other divergent behavior.
Refactored delegation of error message generation

Moved delegation to ActiveModel::Errors#generate_message to
default_error_message and implemented a spec for it.
Fixed typo in spec for error message generation
Refactored error-generation spec to use inline fixture
Ensure that `should` is on the same line as the expectation
Remove duplicated method.
Remove unneeded test that should not have passed.
