Elance's first use of pb-java

Hello I just wanted to share with you a few changes and refactoring I did on this project.
The most important things are that I removed the IDEA IDE specific files, added the Maven's structure and basic pom.xml, added a small Unit test making use of a mocking driver for service calls.

I was able to build and install this project as a library in my own maven local repo and used it as dependency in my project to being able of creating, uploading files, compile, talk and delete a bot.

I hope you find this useful. Thanks a lot.
