Support for proofing

- use core.fileFormat to decide whether a proof file is being viewed,
- don't show the proofing button except for PDF files.
- in a proofing activity, show the page that was being viewed when
  the proof was requested.
- Add extra two arguments to fz_write_gproof_file in the Android build.
