Tags can be created now
added TagList
Tags can be added to objects

Known issues:
id overlap needs to be adjusted
checks don't stay on tags
no way to view tag task lists
deleting a tag deletes references to that tag
should deleting a tag delete all tasks only tagged there?
if task has no tags, remove it
added menus
Tags are a menu on Tasks
tasks are shown by tag

needs a way to display all active tasks after choosing an activeTag
