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.
