TAGS: make shareable and managed by the account owner

In a team environment, the Admin (owner) of the account with sub-agents should be able to manipulate/manage/change/control any of the TAGS and have them trickle down to the sub-agents for use. Many sub-agents create tags that might not follow a scheme desired by the Admin/Owner. Searching for contacts using tags by the account owner becomes impossible as the Admin/Owner is searching by a certain tag and the sub-agent has tagged it differently. (Example: Realtor vs Agent)
