Adds Print support to character sheet pop-ups on Roll20.net
Implements this: https://app.roll20.net/forum/post/1242365/print-character-sheets/?pagenum=1
Feel free to post in that thread, here, or message me on Roll20 if your sheet could use some extra css tweaking.
I can't promise I'll make it perfect, I'm no designer. But I can probably help a bit.
Limitations:
-Doesn't work with pop-outs. I'll have to fix that later.
