Remove unnecessary sections of pmort application.

The new pmort module (that runs behind a daemonizer) is ready to be
added to the project (next commit).
Add the new logic for the pmort application.
Clean up lint from flake8 output.

Cleaned up minor syntax errors, missing imports, &c and have a mostly
running module ready.
Update README.

Added substance to the README information that outlines installation,
troubleshooting, &c.
Add python 2.7 to the pythons tested.
Update parameters to use crumbs.

Switch the parameters logic to crumbs which greatly simplifies this
section of the code.  It also allows us to keep the configuration of
pmort local in each module that it affects.
