Annotate fixtures for nested models

Invoke get options task before annotating migrations

[ fixes #252 ]

This reverts commit 067ce522.

Prefer SQL column type over normalized AR type

fix issue where serializer-related flags weren't being honored

Check if model has skip tag in annotate_model_file

Potentially addresses issue# #167
Annotate_model_file is called automatically on all files in models directory and does not check if model contains SkipSchemaAnnotations tag.

Adds support for foreign key annotations

Test on Ruby 2 versions

Do not add excessive blank lines when source has Windows EOLs

options[:model_dir] seems to be an array now

Add option for classified annotation (id first, timestamps/assotiactions last)

Don't crash on inherited models in subdirectories.
