* it also sets the compatibility level to 7 which was required
   when building for Ubuntu Lucid. This version cannot be supported
   however since its libglib version is too old.

this should simplify building SciTECO for new users

 * compiler and archiver are passed down from Autoconf,
   so cross-compiling should work transparently
 * `make clean` will also clean the Scintilla source tree
 * there is no longer any need for "source bundles" as
   tar balls also contain Scintilla/Scinterm now
 * building from Git is not much more difficult than building
   from a tar ball
 * The versions of Scintilla/Scinterm embedded as submodules
   already contain all the patches necessary (currently none are
   necessary), so there's no need to have patch files in the
   repository
 * INSTALL instructions have been rewritten
 * the --with-scintilla and --with-scinterm site-config options
   have been kept. But they should be rarely necessary now.

so no additional --with-scintilla is necessary when building from
a source bundle

 * prepared for upload to Ubuntu PPA
 * debian package will not be in autoconf source distro
 * will only build as a non-native package based on a source bundle
   that contains scintilla, scinterm and has patches applied
