Add exclusions and change repos

Hi,

I've added exclusions so that maven doesn't pull in so many of the OpenIMAJ bits that you aren't using & to reduce the size of the driver. This is completely untested though - I might have removed something you're using, and also missed some of the dependencies that could be removed. I've also changed to the addresses of the repositories and removed the third-party one as its contents are now included in the main one for simplicity.
