Add Proofing button to Android UI.

Hit the proofing button, and we create a new temporary .gproof file.
We invoke a new version of MuPDF on that. When that finishes control
returns to us, and we delete the .gproof file.

Currently the new version of MuPDF loads the .gproof file, but fails
to generate any pages from it, as we have no version of ghostscript
on the system. Generating this new ghostscript is the next job.
