OK, would it make sense to use this level in the trust calculation?
Similar to the `marginal` ownertrust: three type 0x12 sigs equivalent to
one type 0x13 sig? With the numbers configurable, preferably.

I guess this would make the trustdb calculations a little more
complicated, because both ownertrust and siglevel need to be taken into
account, but to me it feels like a "better" way.

Or am I missing some obvious reasons why this is a bad idea?
