138 button images

added Reggie Rage plus 3 alts
added not-yet-in-database buttons and sets:
Magical Witch Critical Miss
ZoeCon
Cowboy Bebop
KublaCon
Three button images I found missing when I looked through the button info pages:
Al Kwharzimi (or whatever) was misspelled. 
I thought I had added Grist and Cassandra, but apparently I was mistaken. 

Fixes #1269
