ENH: new overview page

The project overview allows us to quickly see how the quality
of a project's key build group(s) have changed over the past
two weeks.

This commit also introduces manageOverview.php, which allows
project admins to determine which build groups should be
included in the overview, and in what order they should appear.

This commit also extends the concept of build groups.  These
can now be defined by substring matching on a build's name.
This option appears as a new tab on manageBuildGroup.

Finally, I updated manageBuildGroup to use the jquery-enabled
drag-and-drop sorting that I used as part of manageOverview.
This removes the need to refresh this page multiple times
when rearranging the positions of your build groups.

SVN revision: 3520
ENH: improve appearance of some new features

Add an option to make the X-axis of our line charts
(as seen on overview.php) to display dates.  Before,
they just said -1, -2, etc., for how many days in
the past this data point represented.

Also improve the display of core vs. non-core coverage
on index.php.  The rows now restripe nicely after collapse
or expand, and a folder icon displays this state for these
groups.
