Feature #1652 (Variant Annotation Tool): First draft of UI: mostactions trigger an ajax call that sends a JSON description of the
query (and what changed); the response is a JSON description of one
or more page sections, with new HTML content to reflect the change.
There is a lot of code lifted verbatim from hgTables that I intend
to libify when the dust settles a bit (search for "verbatim").
Things that work: group -> track -> table selection; reordering
updates notion of which source is primary (needed for filters);
removed sections are reset, and newly displayed sections always appear
at bottom; all buttons do something, even if it's not yet useful.  :)
To do: query execution, position input, output format change handling,
output field selection, and filters.
