now that mazz has changed our tab infrastructure to mimic the L&F you get from the richfaces tabPanel, this is a win.  by migrating this:

* we naturally gain the ability to have subtabs
* can delete SubsystemViewUIBean, which provides JSF tricks to workaround inability to remain sticky on a tab
* remove superfluous database hits and reduce page load time, because right now each time a tab is selected it rerenders (as part of the RESTORE_VIEW JSF phase) the current tab's datatable (which is a hit to the db) and then does another query for the datatable of the tab we're going to

these issues are naturally solved with our custom tab infra because everything is HTTP GET based, which each tab (or subtab) is backed by an independent URL
