first pass at participants functionality embedded into conversations form; removed ownership from participants, now just owned by whomever owns the associated conversation; cannot add participants to new conversation, since a new conversation does not yet have an id; nothing tested
corrected filename of participant_test.rb
fixed participant_test for new ownership functionality
devise views to HAML
replaced hashrockets with colons ("=>" -> ":")
added date to conversations
Merge branch 'master' into participants_functionality

Conflicts:
	app/controllers/conversations_controller.rb
	db/schema.rb
added conversations table to contacts/show
fixed typo in contacts/index
added participants to conversations/index and conversations/show
fixed typo in conversations_participants_fields
made contacts/_form and conversations_form partials without .html extension
fixed conversation tests to include date
Merge branch 'participants_functionality'
added note about broken functionality in participant creation in new conversations
Merge branch 'haml_devise_views'
added uniqueness validation on participants, but this breaks some cocoon/controller functionality
