Update to 0.19.1.

This is a bugfix release, with the only significant change being
changing compiler flags to work around what is probably a bug in gcc,
tending to show up on ubuntu/amd64.
Updated graphics/gimp-ufraw to 0.19.1
Update to 1.10.0.

Upstream appears to have no changelog or NEWS; the included README is
about changes in 1.8.0.  Browsing github makes this look like minor
features and bugfixes.
Updated security/py-paramiko to 1.10.0
