Make HTTP clients only cache graphs as long as we keep them in memcached

We were previously setting Cache-Control: no-cache and Pragma: no-cache
without setting any Expires or Last-Modified headers. This was causing
some clients (e.g., WebKit on iOS) to cache images indefinitely.

We now set Expires, Last-Modified, and Cache-Control: max-age to tell
clients to cache images for as long as we cache them in memcached. If we
aren't using memcached, we tell clients not to cache the images at all.

Register "grep" as a render series function

When using the function grep(series, pattern) the following error is reported:

 KeyError at /render/  u'grep'

The fix is to register the keyword "grep" with the existing grep function in the SeriesFunctions dictionary.

Change initial nav bar config to be collapsed

Our usual use case for dashboards is to view them rather than edit them so it would be better if the navigation bar was collapsed by default when the dashboard is first opened. This is particularly useful for wall monitors that sometimes reboot and need manual intervention to collapse the navigation bar at the moment.
