Version conflicts on bower install

[robnagler]

I got the following version conflicts:

    1) cornerstone#~0.8.4 which resolved to 0.8.4 and is required by cornerstoneWADOImageLoader#0.7.2, cornerstoneWebImageLoader#0.5.3
    2) cornerstone#~0.8.1 which resolved to 0.8.4 and is required by cornerstoneDemo
    3) cornerstone#~0.9.0 which resolved to 0.9.1 and is required by cornerstoneTools#0.7.9

    1) jquery#~2.1.1 which resolved to 2.1.4 and is required by cornerstone#0.8.4, cornerstone#0.9.1, cornerstoneDemo, cornerstoneWADOImageLoader#0.7.2
    2) jquery#~2.2.0 which resolved to 2.2.4 and is required by cornerstoneTools#0.7.9
    3) jquery#1.9.1 - 3 which resolved to 3.2.1 and is required by bootstrap#3.3.7

The versions of the cornerstone* packages are quite old in bower.json. I tried updating them to the latest, but got into more version issues between the cornerstone packages so I just used the following resolutions:

"resolutions": {
   "cornerstone": "~0.8.1",
   "jquery": "~2.2.0"
}

This seems to work.

It would be nice to have some dicom data available for the demo, even one study.
