Added note on boosting systray component process priorities for reliable interactivity.
Made io.tcl display fixed-width aligned numbers.
Added average time waiting in queue (iostat await attribute) to io.tcl
Switched to using plain Tcl instead of Expect for the memory monitor, in the hope it won't have the problems with ballooning memory usage (irony!).
Added submenu for labelled volumes (gleaned from /dev/disk/by-label).
Added option to copy PRIMARY to CLIPBOARD when PRIMARY changes.
Various uncommitted changes
