(v0.5) Various visual improvements:
    - awn applet version is no longer independant of NodeUtil Version
    - details dialog is now kept on top (shows over top of gkrellm)
	- better report about error condition where neither gnome.applet or
		gnomeapplet is available (these are now deprecated due to gtk3)
	- fix bug by setting progressbar value to 1 when usage is >100%
	- percentage label now sits above progressbar rather than next to
		it - gives a wider and more distinctive statusbar
	- 'plan name' label gets word wrapping to avoid insanely wide
		dialog
	- Interface niceties - padding, tooltips, etc
