Issues switching context when same IPM package in multiple namespaces

[isc-pbarton]

If I'm developing the same IPM package on multiple independent namespaces (a recommended flow if hosting individual developer environments on the same instance), it's hard to switch context in the Git Web UI and Settings pages to the right one. The change context menu lists all namespaces, plus all IPM packages in the current namespace. It should also include all IPM packages in other namespaces. IPM package contexts should be prefaced by the namespace in the change context menu. Current workaround to switch context to the other namespace's IPM package is to switch context to namespace, then switch context again to the IPM package.
