* improve AutoPersistent->findFederation(..): try all the possible source
of federation inline: first the nameId in the profile object,
then the userId if present, finally the nameIDs extracted from the dump.
* add i/o error handling to LassoSPKitConfig and comments
* add a promp for the config key 'default_return_url' in LassoSPKitConfigGen
* add new loggin functions: lassospkit_errlog and lassospkit_infolog.
Positive error code from lasso should result in an infolog message.
* import an error handler from php.net but don't use it by default.
* LassoSPKitSaml2: handle SOAP nidmanagement request, move keep/restoreProfile
to common class.
* multi federation works, slo soap works (but signature verification is wrong)
and defederation soap also.
