the main loader

keep midr-mjpeg.mov in pd/doc/media, but remove all the copies of external media files. There aren't any references to those copied files in any of the docs, so they are useless. This means the root "doc" directory is now gone.

This should fix any other missing external dependencies in the OSX app bundle

Get rid of some cruft in the packages/darwin_app Makefile so that we can better see what's going on there.

another attempt to fix #218: get deterministic, sequential behavior when substituting the "nwjs" string for "Purr Data" in the OSX app bundle

first shot at fixing issue #218: error when trying to install on OSX. See if using a temporary text file will work around the bug of plutil creating empty files

replace default nw.js Info.plist with custom one. Not currently using the sed MACROS from Pd-extended (these are shown in the darwin_app/Makefile, and we can add them later for app name and version)

don't build wiringPi
don't run dpkg-architecture
remove reference to AppMain.tcl

fix bugs that were keeping the dmg package from building (leaving out the license for now because it relies on outdated Carbon libs)

* add flag for compatibility with older OSX versions
* change library paths in script so that external dependencies are found
* build with jack support

remove pentium4 arch (I'm on a MacBook Air-- not sure if that would compile on some other Mac)
