[Ovirt-devel] [PATCH server] Add a rudimentary flash chart written in flex framework to summary pages.

First stab at showing real rrd data in flash chart (in this case, memory peak use for last 40 samples of rrd data). Note that to test this, you'll need to get the open flex sdk and compile src/flexchart/flexchart.mxml yourself.
Enjoy,
Steve
