Problem with PRIVATE DEM layers in simulation

[nickhorspool]

There are some issues with PRIVATE DEM layers not being visible in the elevation upload section and also causing problems with starting the simulation as it hangs in INIT status. Jeff has looked and knows more details.

Basically the code to extract the subset of the DEMs over the project area via WCS is doing it un-authenticated, and this leads to the layer not being found when it is marked private. The following error is thrown. Should be an easy fix.
