Use MimeTypes package to determine MIME type

This simplifies the code since we don't have to keep large mappings of extensions and MIME types.

We still keep the ability to override the mappings for:
- filling in entries not present in the package, for e.g. ".azw3"
- picking preferred extensions, for e.g. MimeTypes provides ".conf" as a possible extionsion for "text/plain", and while that is correct, ".txt" would be preferrable
- compatibility reasons
