Permanent Minion Health Bar

Would like to suggest that we enhance the UI a bit for permanent minions (e.g. specters and not consumable minions [e.g. SRS]).

Can take one of two approaches.

- Stack health bars under the tool-tip atop the screen. It's very difficult to monitor specter health in particular because there is no health bar when there is more than 1 minion.

- Modernize the UI a bit and allow us to detach and place into a static location the health bars from permanent minions

Thanks.
