List Animal IDs in order in "Configure Movebank Datasource"

[sarahcd]

When a workflow is shared, the Configure Movebank Datasource summary lists animals in what appears to be a random order. This can make it really difficult to find and select the same animals across a study (for more than a few animals I have to cut, paste, and sort the list outside of MoveApps). These should be listed in alphabetical order.

Relates to #22 , #33 .
