dev-util/geany-plugins: version bump to 1.32 and fix dependencies.

USE flags changed as a result of dependency fixes.

- All plugins need GTK+ at compile time and it is not easy to
  determine which need it at run time, therefore always depend on it.
  Always build plugins with no other dependencies removing their USE
  flags
- pretty-printer is the only plugin directly using libxml2, put it
  behind a USE flag
