Spawner: Large code refactor to remove dependency on plotmarkers.

Most spawner functions can now be called without giving a plotmarker.
Move scanning functions to places.lua.
Places: Cleanup and add more area-scanning functions.
Schedules: Bugfix where schedules weren't being executed due to wrong
"end" order in the do_custom() function.
Data: Moved random data to "data" folder.
Textures: Add 14 male textures and 10 female textures.
Occupations: Small tweaks to "default_basic" occupation.
