As discussed in the aftermath of !85 (merged). This cuts out the defaults export command from the prefs loading pipeline which isn't really needed. While I was at it, I also fixed up some wrong help paths in the default prefs (apparently inherited from Pd-extended), so that these point to Library/Pd-l2ork now.
Tested on Sierra, works fine for me. Default prefs are still loaded if no user prefs are present, and UTF-8 in the prefs also still works.
