ui_plain: automatically lookup mimetype when mimetype-file is set

For sites that do not want to configure mime types by hand but
still want the correct mime type for 'plain' blobs, configuring
a mime type file is made possible. This is handy since such a
file is normally already provided (at least on Linux systems).

Also, this reflects the gitweb option '$mimetypes_file'

Set the mimetype for the specified filename extension. This is used
by the `plain` command when returning blob content.
mimetype-file::
Specifies the file to use for automatic mimetype lookup. If specified
then this field is used as a fallback when no "mimetype.<ext>" match is
found. If unspecified then no such lookup is performed. The typical file
to use on a Linux system is /etc/mime.types. Default value: none. See
also: "mimetype.<ext>". The format of the file must comply to:
- a comment line is an empty line or a line starting with a hash (#),
optionally preceded by whitespace
- a non-comment line starts with the mimetype (like image/png), followed
by one or more file extensions (like jpg), all separated by whitespace
