gkeys/actions.py: verify(), Make it use the configured keydir for verification
gkeys/lib.py: Py3 compatibility changes
gkeys/actions.py: Fix loading of multiple keys in one keydir in installed()

seed.values() returns a dictionary in py3, so wrap it in list() to get the same type data.

Merge pull request #28 from gentoo/pr28

Refactor fetchseed operation, compatibility fixes
python3 fixes
Merge pull request #29 from gentoo/mfix

python 3 fixes
fix wrong urls; minor cosmetic fixes
distinct config and category; add -s to signature now that is not taken

* gkeys was tricked when we passed both --config and --category because these
arguments had the same -c shortcut
* Now that seeds argument became --category added -s to signature.
Merge pull request #30 from gentoo/bugfixes

Misc improvements and bugfixes
gkeys/actions.py: Set the default category to 'rel' if not set
gkeys/lib/py: Fix a missing space in a debug message
gkeys/lib.py: Add --no-permision-warning gpg option
gkeys/ations.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.
