Fixed issue "Can't create new tags on contact #317"
What If I accidently mark a task as completed? #306
Task uncompleted #320, Rename 'Revert complete ' to 'uncomplete'
Merge branch 'task_uncompleted' of github.com:VAIRIX/fat_free_crm into VAIRIX-task_uncompleted

Conflicts:
	config/locales/ru_fat_free_crm.yml
	spec/controllers/entities/contacts_controller_spec.rb
User permissions for uncomplete task
