* Make vertical scale alignment modes work in note layer as well as time-value layer, and several significant fixes to it * Make it possible to draw notes properly on the note layer * Show units (and frequencies etc in note layer's case) in the time-value and note layer description boxes * Minor fix to item edit dialog layout * Some minor menu rearrangement * Comment out a lot of debug output * Add SV website and reference URLs to Help menu, and add code to (attempt to) open them in the user's preferred browser
