Lucas CHOLLET c543a13835 LibCore: Share the mime-type list between the two detection methods
We used to have two separate lists for mime-type detection, one for
detection based on the file extension, and the other one for detection
based on byte sniffing.

This list also contains a general description that will be of use in
`file.cpp`.

To create this list, I had to fill in some gaps as the two lists started
to diverge.
