/****************
* Import the public keys from the given filename.
* Import is a somewhat misleading name, as we (only) add informations
* about the public keys into aout trustdb.
*
* NOTE: this function is not really needed and will be changed to
* a function which reads a plain textfile, describing a public
* key and its associated ownertrust. This can be used (together
* with the export function) to make a backup of the assigned
* ownertrusts.
