Fix inconsistencies in guest nick name generation
When the setting net/nick is empty, HW generates a guest name. But there were several problems:
- Team name did not match guest name
- Random guest number was re-rolled multiple times, causing inconsistencies
- Guest number was often too large (now capped at 99999)

Add Randy's Candy_v1 as an upgrade to the Cake theme, add Cake theme to list of selectable themes. Also add forgotten Hoggywood CMakeLists.txt.
