Fixed JSMN bug, added release, Started visual scripting tool

Found a bug in which JSMN doesn't properly initialize tokens in Release
mode. Added a method to initialize JSMN tokens.

Added release executable so people without VS can actually use this

turned keyboard keys back on by default, since I can't assume a user has
an XBox 360 controller lying around

Started writing a visual scripting tool for the ActorScript VM. This is
going to take some thought.
