Patterpad 0.3.0

Added

• Auto Rebuild (opt-in): recompile the .patterc bundle a moment after you stop editing, so the
  on-disk build stays current without pressing Publish Bundle. Toggle it from the Publish menu
  checkbox or Project Settings ▸ General. It only writes when the compiled bundle actually
  changed, and silently keeps the last good build if the project is momentarily invalid mid-edit.
  Off by default (best left off if you commit the bundle to a lock-based VCS).
