Window docker - turn any window into panel

[Keith Poole]

Hey Mike,

Great work, and I'm sure there are many developers available to help you with tips or solutions to your problems. A lot of them are quite busy though so you have to be patient.

Keep up the great work though!!

I have to terminate docker and restart with same options, including window ID (currently it supports only such dumb rule - more rules have to be added later), and only after this step window is visible.
