Modified resource retrieval from gs_catalog in layers/models.py and added assumption that store exists within workspace in updatelayers to improve speed.
Merge remote-tracking branch 'upstream/master' into layer_geoserver_speedup
Updated code to obtain gs_resource in models(layers) to use gsconfig get_resource function with workspace and store passed.  Fixed issue with gs_slurp and error handling for nonexistent workspaces
Remove some unnecessary debug lines
Fixed issue with var reference names in get_resource() call in Layer.store_type property function

Closes #1368
Altered WCS link generation method width/height

Fixes #1356; WCS links should now return their native grid height and width
based on the WCS describeCoverage spatial grid.
Also changed how links are generated so that when fetching URLs on
very coverages the server does not need to issue several getCoverage for the
 entire grid extent of the coverage, which would ordinarily bog down the server
for large coverages.
added some web links

Ensure proper configuration when using the geonode.importer backend.
Add comments on DEBUG and DEBUG_STATIC in the local_settings.py
Updatelayers -w option nows correctly skip any layer if the workspace does not exist.
This fixes #1378. We should refactor the whole thing, but for now it works.
Removed a small typo.
Enable resource link selection in document metadata form.
