ObHack 005c released

I have released ObHack 005c today:

• Bugfix: The reason why the outdoors theme occasionally had a Wolfenstein door was because there were no doors marked for the nature theme, so ObHack would just choose any door at random. Fixed (Andrew had this fix for Oblige 0.97, but it took a bit of prodding to figure out which diff was the fix)
• Minimize the use of prefabs with Wolfenstein textures in non-Wolfenstein levels
• Memory leak in RNG plugged
• FLTK updated to use FLTK-1.1.9 (which actually makes the source tarball smaller; I also don't like having the code use a developer snap of some library to compile)

It can be downloaded at samiam.org/slump.
