Misc fixes
gkeys: Update config file

Rename MAIN section to DEFAULT for automatic variable substitution to work
in sub-sections.
Add a new seeds subsection and rename the seed files for better user interaction.
gkeys: Update seed action options

Remove category option as it is not needed.
Add file option to installkey as it is needed in the listseed() call.
gkeys/actions.py: Make 'rel' category the default in listkey()
gkeys/cli.py: Update option help messages to better reflect how they may be used
gkeys: stub cleanseed, cleankey options
gkeys/actions.py: Move ssl-fetch import to action function it is used

This reduces the import load to only be for the function it is used.
It also removes the import on a system that does not have all the dependencies installed.
