Expand options to support 3 possible sources of octave * configure.ac: modify --enable-stable rule to --enable-octave=source (stable,alpha,default) * Makefile.am: modify OCTAVE_TARGET based on octave build value set in configure. * index.html: added master-octave information. * src/default-octave.mk: new file. * src/default-octave-1-docinstall.patch * dist-files.mk: add default-octave-1-docinstall.patch default-octave.mk * binary-dist-rules.mk: use OCTAVE_TARGET to decide on tarball/installer name
