Annotation position defaulted to 'before'. Bugfix: annotate_models.rake uses string instead of symbol.

Fix options parsing to convert strings to proper booleans. Change annotate to use options hash instead of ENV.

added '-R' option to require additional files
ignore unknown macros ('acts_as_whatever') (with specs!)

use model_dir parameter in remove_annotation as well; remove obsolete (and confusing) annotate.rake file

fix the dependencies so it doesn't fail when multiple version of Rails is installed, reported by kuroda

* update gem with newgem
Add my plugin addons:

Annotates in the end by default.
