Add mechanism for the detectors to be able to tell the source of the
data changes.

  Support for tx_Source property on database handle. Can be
  used by detectors to find out the source of a change in an auditor to
  block changes arriving by unauthenticated mechanisms (e.g. plain email
  where headers can be faked). The property db.tx_Source has the
  following values:
  * None - Default value set to None. May be valid if it's a script
    that is created by the user. Otherwise it's an error and indicates
    that some code path is not properly setting the tx_Source property.
  * "cli" - this string value is set when using roundup-admin and
    supplied scripts.
  * "web" - this string value is set when using any web based
    technique: html interface, xmlrpc ....
  * "email" - this string value is set when using an unauthenticated
    email based technique.
  * "email-sig-openpgp" - this string value is set when email with a
    valid pgp signature is used. (*NOTE* the testing for this mode
    is incomplete. If you have a pgp infrastructure you should test
    and verify that this is properly set.)

This also includes some (possibly incomplete) tests cases for the
modes above and an example of using ts_Source in the customization.txt
document.
