Spell Channeling Bar

What's this mod?
It displays a bar that indicates the progress of channeling spells. It displays how long your hero has been channeling a spell for, and how much longer until the spell's completion.

While channeling, the bar is yellow. When your hero stops channeling (either through spell completion, or being interrupted), the bar turns purple.

When the bar is not being used (ie. your hero is not channeling anything), it will be hidden so that it does not obstruct the interface.

Also works for items.

Also works for creeps (the vulture man), and allied heroes with shared control.
