Add support for mime type registration and lookup

This patch makes it possible to register mappings from filename
extension to mime type in cgitrc and use this mapping when returning
blob content in `plain` view.

The reason for adding this mapping to cgitrc (as opposed to parsing
something like /etc/mime.types) is to allow quick lookup of a limited
number of filename extensions (/etc/mime-types on my machine currently
contains over 700 entries).

NB: A nice addition to this patch would be to parse /etc/mime.types
when `plain` view is requested for a file with an extension for which
there is no mapping registered in cgitrc.
