Updated the Chem Dispenser UI with an Energy bar.
UIs attached to the Chem Dispenser will now update on recharge(), recharge now recharges 1 every 15 ticks instead of 2 every 30 (to make it feel more fluid).
* Visibility updates (now uses line of sight).
* Added displayBar() template helper for displaying progress/health bars.
* Added new health bars to Nano UI Cryo.
* Added Eject Occupant to Nano UI Cryo.
* Nano now handles Topic for the src_object, allowing it to only allow interactions with UIs that have a "STATUS_INTERACTIVE" status/visibility.
Removed user << browse_rsc() entries as they caused the delay. New assets (stylesheets, scripts, templates and images) have to be added to the client's send_resources proc or they will not exist on the client.
