Unix Pageant: provide public-key extraction options.

Browse Source 
I've decided against implementing an option exactly analogous to
'ssh-add -L' (printing the full public key of everything in the
agent). Instead, you can identify a specific key to display in full,
by any of the same means -d lets you use, and then print it in either
of the public key formats we support.
