Back-fill

• In the Backfill dialog, the 'play' button  has been removed. The backfill dates gets set as soon as the user makes a date change (no need to push a play button).
• Selecting single tags using the checkbox and the single 'Move Selected' button now works correctly.

Creating Connectors

• Currently, Gateways can only be added under the 'Base(root) Organization'. There is now a 'house' icon on the base organization and a tooltip that identifies the instance as the base organization.
• Currently, the Gateway-Connector relationship is one to one: you can only create one connector per gateway. This is now enforced in the UI.
• The (+) button on a connector has been removed: you cannot 'add' anything to a connector.
