Update to Keyboard PNG (Version 2)

While I'm still (very slowly) working on the other sets for the update, I decided to at least release the 2nd keyboard PNG so anybody who wants or needs the extra keys can go ahead and use them.

Although the text on one set was kinda hard to make work, I also included one with icons/images that I believe reference the keys needed.

Hopefully you all like it and I'll be preparing the rest 2.0 later. It'll mainly be slightly different buttons with a different a few colour palettes. Inspired a bit by arcade fight sticks. 

• added insert, home, pgup, pgdn, delete and end keys to keyboard
• some extra keyboard/mouse/cursor images
