representing the interface for, well, MIME sniffer add-ons.
* Implemented the respective add-on manager and make use of it in
the MIME database code. Unfortunately the MIME DB code completely
lives in libbe.so and hence I had to put my code there too.
IMHO we should (one day) remove the direct (read-only) MIME DB
access from libbe and move everything into the registrar.
Currently the add-on manager supports built-in add-ons only; it
doesn't really load anything from disk ATM.
* Added a built-in text sniffer add-on to the registrar. It's based
upon the BSD file tool code.
This closes bug #250 (plain text files are identified as such, now).
