Add pgp public key and refer to it in our security disclosure method

The idea behind this is to make sure people that choose to use email to let us
known about a potential security issue in Pidgin encrypt the content of the
emails using a set of pgp keys of trusted Pidgin developers. For now we only
have the pgp key of grim but more keys can easily be added later on.

At the same time, since Hugo does not currently have a built-in shortcode for
linking directly to static resources, I had to add a new shortcode for doing so

Testing Done:
Ran `dev-server.sh` and made sure content looked as intended and links worked.

This is an attempt to document the various XMPP Extensions
([XEP's](https://xmpp.org/extensions/)) supported by XMPP protocol plugin in
libpurple. Please note that this list is **_incomplete_** and that libpurple
almost certainly supports more XEP's than are listed here!
