Migrate Ant build system to Apache Maven build system

[AndrewSmart]

I didn't notice Maven was used initially. The initial build script will download the official binaries if they don't exist. *Currently ant. *Shouldn't download the official OpenCyc API jar; sould call the following Maven build script. The second build script (to becalled by the first) will build the OpenCyc API. *Currently Maven. I like Ant better, but they're using Maven.
