Annotate controllers and helpers

Fix :ignore_columns option in "auto_annotate_models" task

Correctly find annotate_models task in an unmounted engine

Add root_dir capability for multiple roots

Fix: Ignore columns not respected when the rake task is invoked

rubocop friendly template

single-quoted strings and redundant curly braces around a hash parameter

Annotate non-model test files: #286

Make --w option work

Accept wrapper default params

more documentation for auto-annotate and rake tasks

the docs for auto-annotating were kind of buried inside the Rails Config section, so I extended them and added a reference to them inside the Usage section

Update README.rdoc

Remove new line before annotation wrapper closing statement

Set model_dir to ["app/models"] if not set (fixes #265)

Runs annotate on 'rake db:rollback' too

show foreign keys when run on rake task

ignore default value for jsonb

Quote each value in default arrays

Previously, quoting an array fell back to `inspect`, which is ok for
strings, but not good for BigDecimals, for instance.

Annotate fixtures for nested models

Invoke get options task before annotating migrations

[ fixes #252 ]
