The SolrConfig.Initializable interface was introduced as part of SOLR-215
to give Token(izer|Filter)Factories access to the SolrConfig (i believe
just because StopFilter and SynonymFilter needed getLines)
I can't help but wonder if it would make more sense to replace this with
something like "SolrCore.Initializable" ... you can get a SolrConfig from
a SolrCore, but you can't get a SolrCore from a SolrConfig.
This would be a big help for things like SOLR-319.
Is there any particular reason why it would be bad to pass the SolrCore to
the init method instead of the SolrConfig?
