fixed an issue where the jvm tab will never show up
removed active counters from cassandra operations chart
Added onUpdate hook to graphbox

Some boxes will show textual data next to the graphs. For them to sync
together I have added an onUpdate hook to graph box.
This hook will fire up when the graph is updated, allowing the views to
update the texual data accordinly.
graph box view no renders jqplot to an inner div in the box. allowing extra details in the box
Added a view for graphs with textual information to their side

As designed in the latest HTML, some boxes will have both a graph and
textual data.
I have created a view to represent such charts.
added the new side text graph box to the makefile
Changed operations graph to show the active counters as textual data

The active counters rarely move and should not be presented as live
grpahs. Instead the operations box will levearge the new chart with text
side view to present the active counters in a live updating textual format.
changed all references in cassandra operations graph from write to mutation
added base class for cassandra related graphs for code reuse
Changed Cassandra graphs to present value per second with derviatives

All the graphs that include derivatives now do a more correct
calculation, taking in account the time interval between 2 reads as
well as the difference in value.
Fixed wrong build order
