Modals should "manage" focus

[theKashey]

Any "focused task" should trap focus inside, and not let it get out.

Right now:

1. It does not set a focus on modal content, keeping it on the button one clicked to open a modal
2. Does not prevent leaving modal. "tabbing-out" from it.
3. Lucky we - it closes modal on any action "outside"
