Chart Library Part 1 of 3

Add preset charts to the LTM sidebar, and allow LTM charts
to refer to sidebar for config instead of the local config.

In this way we can have a chart that changes as we select different
charts in the sidebar and remove the need to have lots and lots of
different charts on the tabs.

But it still allows for the old way of doing things -- just adds
another type of flexibility -- for instance a user could add
charts with set date ranges but no specific curve setup so they
could havethis year, this month, last month charts that change as
charts are selected in the sidebar.

This first commit just adds the sidebar item, next we will update
the LTM chart to refer to it in part 2 and then in part 3 we
will add functions on the sidebar to manage the chart presets in
the same way as in LTMTool.
