Enhanced version with history, auto play, keyboard control, fixes

[gingerbeardman]

I recently added a bunch of functionality and fixes, mostly to the demo app:

• fix: getDirectoryItems (from a PR)
• fix: off by one sample length error in sfxr.lua (from a PR)
• fix: space bar was not playing the sound
• fix: selected wave form was being ignored (sounds were always square wave)
• fix: loaded wave form not updating the interface (but sound was playing correctly)
• add: clone method added to sfxr.lua
• add: history form with list of previous sounds, save current, and undo/redo
• add: “play on changes” so that any time you adjust a sound it plays automatically
• add: keyboard navigation in file picker (A–Z: jump to files, Enter: choose, Esc: close picker)

...is there any interest in a PR for these? I'm only asking because there are several long-standing PRs already.
