Fix login removing graph controls.
Make saved view use same templates as display_graphs.

--Still needs an additional widget id to identify the particular saved graph.
Add admin tool fields for saved graph related objects.
Add widget id so that saved graphs display.

Needed to remove graphs_list since the needed code in savedView and display_graphs was
significantly different (savedView needed to use the widget with related object to get the
  datastream and widget number).
Change exception caught to AttributeError.

Exception being thrown was not the one expected.  Need to do this to allow users that are not logged in to
view the graph.
Make sidebar refresh on login.
Make sure date_pickers are set whenever the graph controls are loaded.

This is on initial page load and on login.  There are no other places that I know of that render this
at this time.
Make start/end date format consistent.

getRanges() was using a totally different format than the date_picker.
Make saved graph render over the correct time frame.
