[reportlab-users] Problem printing with lulu.com

[Andy Robinson]

We've decided on a couple of changes here.

- those people printing in environments where all fonts should be
embedded should have a way to register not only a base font but also a
font family (as we need bold and italic) on startup
- getSampleStyleSheet() can then use this
- anything else needing a default font will take it from the config

Hopefully this will eliminate stray occurrences of Helvetica and
Times-Roman, and still make it easy enough to get a usable stylesheet
without making a copy of it.

Robin will post the list when this is in place
