Improve MIME handling. This patch is based on Eugene's patch, but

with the following changes:

1) Don't make a mime_types.h 'cos we should avoid creating variables
   in header files,
2) Use strrchr to find the extension, rather than strchr,
3) Slightly simplify the mime-type matching loop.

any goof are likely to be mine. Note that there are links to more
improvements by Eugene in the PR.
