VDI-2229: Avoid entering 2 times to resize events

We were always executing the default resize event handler for the selector ".wm-resize".
This was not correct because actually that was the bottom-right handler.
This caused that any resize event was executing it's own event handler and the "bottom-right" one.
Don't emit move signal if we are only moving
Created resizer container

This class creates a container with borders on top of a window and can
move and resize.
While resizing don't move the window, move a border

We do not want to resize the content until mouseup. That's why we show a
"resizer container" (a container with just a black border) while
resizing.
