Add .doc NEWS type

[thijs]

Currently 95% of the documentation tickets are marked as .misc changes, but might make sense to have a .doc type file instead.

Yea, I think this is a good idea.

The tool supports .doc files in the branch. Suggestions for better presentation welcome.

Once this is accepted, we need to update the wiki page that talks about news fragments to mention this new type and give some guidelines for what to put in .doc files. We'll also need to update enforcenews.py to recognize this type.

1. Please remove the unused local basename = ticket.basename()

Everything else looks good. I am happy with the current presentation.

Add support for a new kind of news fragment, .doc. These are aggregated into a new section of the news file by the news builder.
