  a jail.

- For string comparison for key values in Jails get() method

- Create and pass a JailsEditForm to the jail edit html template

- Add notifier method to return path of pbi upload location, as well as
  debug logging for pbi installs.

- Use new notifier pbi upload location in the jail view for installing
  plugins.

  first.
