improve the external dialog api by adding an additional argument to specify the input type, refactor grid dialog to the new interface

fix reference to "scope~" classname in g_editor, refactor pdgui.js to fit the new cyclone color methods

* the commits from Pd-extended Sourceforge were then (selectively) merged
  with the ported gui code.

fix up Windows-specific build script to just rsync the pd/doc directory. At some point we need to use makefile.in for Windows just like Linux and OSX do...

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.

remove patches from "messageoddness" directory that were either fixed earlier in Pd-l2ork or are misleading/wrong

repo cleanup: remove tcl/tk build infrastructure and scripts, old patches, automated build scripts for pd-extended, old gui plugins, and unnecessary install-time dependencies

update contributor guide, making clear a prototyping language cannot itself be build out of prototypes

port all relevant externals to the new loadbang interface. Unfortunately it has some #defines hidden in g_canvas.h, so we port that macro individually to each affected library.
