c4d46c7035
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.
