allow add_mime to fail

add_mime nows allocate dinamically copies of the passed strings, so
that we can actually free what we parse from the config file.

This matters a lot especially with lengthy `types' block: strings that
reach the internal mapping are never free'd, so every manual addition
is leaked.
