Don't look for BAMs on HDFS

[ihodes]

Instead, BAM URLs are now just HTTP(s) URLs pointing anywhere.

Addresses #791

If we don't want to break links on the deployed Cycledash when we push this change, we'll need to add http://hammerlab-dev3.hpc.mssm.edu:9876 in front of all our existing BAM URIs.

It's a URL now; previously it was a URI (just the path on HDFS). A URI is a subset of a URL, so I figured I'd keep it the same on the backend http://stackoverflow.com/questions/176264/what-is-the-difference-between-a-uri-a-url-and-a-urn
