Now using sshKeyDist.sshpaths to determine location of SSH binaries.
Because I'm testing scripts from the command-line (not building with
PyInstaller etc.), I'm using a dodgy method to find the sshKeyDist
module in the parent directory (adding it to sys.path) for now.

DeleteKey module now uses a class.

Fixed a bug where InspectKey could display a non-Launcher fingerprint
from the agent, instead of the Launcher fingerprint.
