Error when trying to navigate to a specific planet under collections

[astrofrog]

To reproduce:

• Go to http://worldwidetelescope.org/webclient/
• In the list of collections, click on Planets/Moons
• Click on Jupiter

Nothing happens and the console includes the following error:

angular.js:13920 TypeError: d.get_camParams is not a function
    at Object.h [as clickThumb] (wwtwebclient.min.js?v=5.3.66:6)

The problem is in clickThumb in factories/ThumbList.js. The item being clicked is an ImageSet with DataSetType = "Planet" and ReferenceFrame = "Jupiter", and when lookAt = "Sky" the existing logic doesn't handle the necessary state transition.

Looks like there's also an issue where the logic in util.getIsPlanet is incorrect — testing for get_rotation is basically a test for whether the item is an Imageset instance, which is not the right thing to check.
