[Bryce Harrington <bryce@xxxxxxxxxxxxx>]

Bugs that are filed by or appended to by apport have key:value pairs
inserted into their descriptions.  The patch below enables arsenal to
parse this data out and provides it in a dictionary structure.

Posting to the list for comment before I merge it.

Also, attaching an example script for testing purposes, which outputs
the bug properties in JSON format.

Comments welcomed.

Bryce
