Fit video to screen plugin.

this solves issue #37, so i decide to write the plugin myself, and add it to controls. 
The plugin have 3 options, 
Cover: should resize the video keeping the aspect ratio until it fill the screen. You loose some borders.
Fill: will resize the video until it fill all the screen, this doesn't keep the aspect radio.
Default: The video will be contain by the screen without resizing.

Please give it a try and merge it.
