Allow Color Choice For Disabled / Un-Powered Actions

As of Tasker 5.0+ when an Action in a Task has been disabled (un-powered) the only thing to designate it as so is an olive-drab color bar to the left of it. 

(Color may be different depending on theme).

HOWEVER this doesn't make it very obvious that the Action has been disabled.

In the future - this bar color should be configurable in Preferences AND there should be an option to have that entire Action greyed-out.
