WebSubmit: file stamper option to copy metadata

* Introduces the "--skip-metadata" option to the file stamper.
  If enabled, the file stamper will not copy the PDF metadata from the input
  file to the (stamped) output file. Otherwise, the file stamper will attempt
  to copy all PDF metadata.  (closes #1569)

installation: README.rst with build status badges

* Adds new documentation file README.rst which is essentially
  identical to README, plus contains extra links to Travis build
  status badges, bringing them onto the GitHub home page.

  This is done because apparently GitHub only recognises file
  formats by extensions, so badges cannot be easily introduced
  into plain README files (that we still keep as per GNU autotools
  practices).
