fix shift-ENTER for newer atom version,
and shift-C for clear post window now works
change(post-window): do not echo repl input to post window
style(post-window): colorize some scsynth server errors

its a bit hacky, just reg ex replacements
style(post-window): better state notifications (compiled, ready)

they look a bit more "adult"
style(post-window): minor tweak to the fold icons
minor
feat(sclang): dynamically write config file for sclang using supercollider.yaml
and adding the atom-supercollider support classes in ./scclasses

this means no need to install a quark or update it. it just works
