fixed bug regarding evaluated node graphics. some other cleanup.
fixed a bug where the fairy would also spawn at (0,0) if a search map
was the first one chosen. also fixed a big thread bug where i was
forking off a new thread each time a map was called without terminating
the currently running one. might still be leaking a thread or two the
first run, but the pool stays consistent after that. cpu usage is
greatly improved!
zooming more or less works, just trying to make it work with a
vector...the result is so drastically different it's confusing
