Feature Addition: Added Ability to Run Launch Configurations in Eclipse from vim

Hi,
I added a few commands so that you can now run launchers in eclipse.
The commands are:
ProjectRun
ProjectRunDebug
ProjectList

ProjectRun and ProjectRunDebug have autocompletion setup, and allow running based off of the index of the launch configuration or the name. 
ProjectList gives a nice formatted list of the launch configurations.

Also, added a command in org.eclim.core to implement the Eclipse functionality.
