A dashboard enabled file in local/enabled is not able to appear before,
or inbetween any core panels.
The list of panels appears to be intended to be sorted by file name,
but all files in /enabled and always presented in the nav ahead of
any files from local/enabled, no matter the file name.
This appears to be a bug in util/settings.py that does an rsplit to
separate file name from path, but accidentally uses the full list of
split items, instead of just the file name.
For example, a file with __name__ of
'openstack_dashboard.enabled._1040_project_volumes_panel' splits into
['openstack_dashboard.enabled', '_1040_project_volumes_panel']. When
this list is fed to cmp(), it will always come before a panel in
local/enabled such as
['openstack_dashboard.local.enabled', '_0001_my_new_panel']
