Standardize zotz sprite sizes

[Ealb]

Zotz basesprites are 45x32 - while the Dom5 engine handles this without distorting the images (yay progress!), they align really oddly in recruitment screens and even show up differently (in terms of spacing and placement w/in grid squares) on the battle screens. It's not a devastatingly high priority, but at some point zotz need their image size standardized to 64x64. This will take a fair amount of data file and gear sprite adjustments.
