bugzilla: add xmlrpcemail submission for Bugzilla 3.6 email interface

Some of the formatting details required for bug submission via email
changed between Bugzilla 3.4 and 3.6. Bugzilla 3.4 requires lines of
the form '@fieldname = value', while 3.6 wants '@fieldname value'.
Also the field @bug_id in 3.4 becomes @id in 3.6.

Bugzilla up to and including 4.0 also recognises the 3.4 format. To save
surprises in the future, check the Bugzilla version and use the 3.6
format from all major versions >= 4. At some point we will
drop support for Bugzilla prior to 3.6 and support the new format only.
