spacebar in editmode. Previously all default actions were filtered, and
this broke OSX keyboard shortcuts.

remove OSCx/configure (should have been done in last commit, which was only adding a line to the oscx_clean target)

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...
