[BUG][PL] Exit pause after rewind in playback mode

[Guigui]

NL CE 1.1.2

When using Playback mode : pause the game then rewind to the beginning with the F1 shortcut. At this point I can not exit the pause with the [space] shortcut key, I have to use the pause button in the toolbar.
Not a big issue but may be worth mentionning.

I think this might be a symptom of a bugfix (NLCEPlayer commit 8dbba16) intended to prevent Preview/Postview Screen key presses and mouse clicks from making their way into the game when auto-skip is active. You'll probably find that if you start up Playback Mode and un-check 'Auto-skip Preview & Postview Screens', this bug will disappear. Or, press F1 to restart, skip forward 1 frame, then you'll be able to unpause using the [Space] bar (or whatever key Pause is linked to).

This is clearly not ideal. I'll try out a different fix for the 'delayed input' bug, ensuring that frame 0 will allow key and mouse presses again (when in Playback Mode + Auto-skip).
