Changes from v1.06 to v1.07

Features:

-Added an A<->B feature for videos (to replay a specific part of a video over and over).

Keys are:

Z: setting point A

X: toggling feature on or off

C: setting point B

Fixes:

-Fixed the zoom (it was doing weird stuff)

-Fixed Esc key so it only takes you out of fullscreen

-Fixed the X button to quit (it was working partially, going from fullscreen to windowed instead of quitting)
