add acts-as-taggable gem for reagents and equipment tagging
Add taggable migration
Add tag_list to Reagents controller and acts-as-taggable to R model
Implement tagging for the reagents model
Try to add polymorphic association to reagents, went total fubar in specs, scaled back
Update schema.rb to remove consumable references and add user_id and index to reagents
Update reagent model and specs all tests passing, no more polymorphic bullshit
Forget polymorphic assocations for reagents for now, stick to what I know
