gwyddion: 2.48 -> 2.55 (and add options)

Gwyddion has a large number of optional dependencies. In this update,
those dependencies have been added with options set mostly to true,
and an option (default false) for working Python 2.7 support in the
program and in Python has been added. I have also added myself as a
maintainer as no maintainer is currently set.
