mdPanel -allow clickOutsideToClose works with propagateContainerEvents

[ivan-zakharchuk]

Actual Behavior:

• Currently mdPanel by default use body element as parent and have wrapper(.md-panel-outer-wrapper) with styles { height: 100%; left: 0; position: absolute; top: 0; width: 100%; } so we must use propagateContainerEvents: true (pointer-events: none;) to be able to interact with page elements. But in this case clickOutsideToClose:true doesn't work at all.
• When clickOutsideToClose:true is specified along with propagateContainerEvents: true it should close our panel when user clicks somewhere on page, but also propagate this event to a target.

CodePen (or steps to reproduce the issue): *

• You could observe this in demo example in docs for 1.1.0

Here is a codepen where you can see those 2 options set to true : http://codepen.io/anon/pen/EgjpkP
You can see that the dialog panel never close without propagating clicks and that the select panel propagate the click but do not close (you can have fun clicking the select button multiple times)
