v3

The biggest update yet!

Features:

• We now have a CAPS LOCK KEY! YOU CAN NOW TYPE THE SAME EXACT LETTERS YOU COULD BEFORE, BUT LOUDER (credit: @noahjutz)
• Press and hold the "a" and backspace keys to SCREAM FASTER (and delete faster) (credit: @noahjutz)
• Minimalist mode: disable the space and caps lock keys in case all these new buttons are too confusing

Bug fixes:

• The invalid character error message was inadvertently removed in v2. It's back now
