Add Maven Support and Add to Maven Central

[MTrop]

This project should probably end up in Maven Central at some point, but I was lazy about it/didn't anticipate demand.

Stuff that needs to happen on my end:

• [ ] Add the net.mtrop group to Sonatype/Maven Central (for this project and potentially others).
• [ ] Convert the Ant build scripts to a POM.
• [ ] Push to Maven as the doom artifact.
