Subject: [PATCH] Add a "screen" subcommand to krbroot

I have screen profiles for "all scripts web servers", "all scripts hosts",
etc., which means I often want to run screen with root tickets and pass it some
options. This makes that easy.

This uses the technique from ASA DB commit
08d4fa6744d2785023666d10a1936460811fcdb2
(https://asa.scripts.mit.edu/trac/changeset/08d4fa6744d2785023666d10a1936460811fcdb2)
to pass commands possibly containing metacharacters through pagsh without
quoting issues.
