Merge branch 'core-updates'.

gnu: Remove 'guile-reader-for-guile_1.8'.

This was a useful example back in July 2012, but not very useful
beyond that.

* gnu/packages/guile.scm (guile-reader): Turn into a plain package.
  [source]: Use mirror:// URI.
  [inputs]: Use GUILE-2.0.
  [arguments]: Use the site/2.0 directory for --with-moduledir.
  (guile-reader/guile-1.8, guile-reader/guile-2.0): Remove.

gnu: Remove now unneeded 'localedef' invocations.

This is a followup to commit b0fd2bd.

* gnu/packages/gawk.scm (gawk)[arguments] <install-locales>: Add comment
  on why we leave this here.
* gnu/packages/guile.scm (guile-ncurses)[arguments]: Remove
  'install-locales' phase.
* gnu/packages/swig.scm (swig)[arguments]: Likewise.
* gnu/packages/python.scm (python-matplotlib): Remove 'LOCPATH' setting
  and 'localedef' invocation.
  (python-scipy): Likewise.

gnu: Move guile-charting to (gnu packages plotutils).

This removes the dependency from (gnu packages guile)
to (gnu packages gtk), which potentially reduces the memory/IO/CPU
footprint given that 'guile' is used during bootstrap.

* gnu/packages/guile.scm (guile-charting): Move to...
* gnu/packages/plotutils.scm (guile-charting): ... here.
