Continued with pp2lino.

New field `JobType.remark`.
Field Job.remark is now a TextField (was a CharField).

New tables 
:class:`lino.modlib.jobs.models.Function` and
:class:`lino.modlib.jobs.models.Sector`
(and Foreign Keys to these in 
:class:`lino.modlib.jobs.models.Job`
and
:class:`lino.modlib.jobs.models.JobRequest`).

New table 
:class:`lino.modlib.jobs.models.Offer`.
pp2lino doesn't create any Jobs at all.
