Memory leakage

I’m pretty sure Seraphiel is currently leaking memory like a bucket with no base. I’m going to be fixing that in 0.2b3. Hopefully the Halfling/Elf buildings page too, but getting out a fix to the memory leakage is top prioirity. For non-developers, a memory leak is basically a problem that results in the program using up far more memory than it should be (it’s not a security problem, just a performance one, in case anyone was worried).
