extensions should be supported

it would be very nice to be able to use the GIS extension, the old and new network extensions, arrays, tables, matrices, etc.

GIS extension in particular is #68

I was able to trivially get extension support going by just making an extensions symlink at the root of the Play project directory. However, stuff like the GIS extension that attempts to load to a data file relative to the model... that's going to take more effort. I suspect that some changes have to be made to the NetLogo extension manager to accommodate for the fact that we're loading models from URLs.

I think Git supports adding symlinks to version control? if not, you could add code to the build definition that makes the symlink

[TheBizzle]

Yes, it does support that, and that's fine, but the problem isn't really solved until extra files can be loaded, which isn't something that we can easily handle with symlinks, I think.
