Customize-able base generator, with added features

This is based on barmint's excellent base generator, with the addition of the ability to cut out a recess for any models mounted on existing basing. That way, you can glue them to this base and then paint and blend it in, so you don't damage the model removing the old base. I found myself with lots of micro armor already mounted - infantry on pennies, vehicles on plastic card, etc. This allows me to base them consistently, and I use the rear bevel to glue a name and unit designation.

I've also included a few pregenerated bases, just for giggles.
