Opacity + bug fix

Added an opacity slider, since using a filter doesn't work.
Fixed empty lines appearing when disabling mouse input and pressing any mouse button
Fixed crashes when pressing undefined keys while using input-history

Input History

This release contain's a new source type called "Input History"
It displays most keyboard shortcuts in a chronological order.
It's also not completely finished and I'd like to get some more input on it.

Small fix

Fixed textures not loading correctly when they spanned over multiple rows

Qwerty + fixes

Fixed some issues when loading larger layouts
Added qwerty layout (Only main keyboard and function keys)

Version 1

I got all features working except for the scroll wheel which is tricky.
Only thing left is Linux support, but for now this'll do.
