You shouldn't be loading all the files. The database is split so you only
load the bits you need, as you need them. This should be much faster than
loading the whole database.

These are customisations for old applications that don't support the new
system yet, yes? Ideally, the user should not have to modify the database.

There was a suggestion of inheritance. Eg 'image/svg is-a text/plain'.
Possibly however, the two generic rules 'text/* is-a text/plain' and
'(^inode)/* is-a application/octet-stream' cover all the useful cases.
Plus allowing the user to manually specify loading any file into any
application, of course.
