Compact FM editor with alternate envelope display (#210)

Browse source 
* tab names, env size, ssg tickbox

* Env size, ssg tickbox, tab names

* Horizontal line showing sustain

* Compress the envelope horizontally

* Draw release as shaded triangle in background

* Envelopes now scale with TL

* Draw two lines to SL, changed env horiz. scaling

* SL line again (yes, the env clips thru the window)

* Slopes of DR and D2R stay constant when SL changes

* revert horiz SL line behavior

* Minor code cleanup

* Handle cases where AR, Dr, or D2R are 0

* FM editor fits without vertical scrollbar at 1080p

* Reverse sliders so louder/longer is on the right
