Sidebar "default" sort should show newer locations on top

[jfrankl]

In the application, when using the "default" sort, newer locations show up on the bottom of the sidebar. The issue here is that when a user adds a location, it can be hidden beneath the other locations, forcing a user to scroll down with each add. If those locations were added to the top, they'd be easier to see.

This will lead to the markers appearing backwards (in reverse order) in the sidebar, for example C, B, A instead of A, B, C:

Is that alright?

@jfrankl can you confirm that the above is an acceptable consequence for having new apiaries appear on top?

[jfrankl]

Yes, I think that's preferable.
