Feature/seqware 1985 seqware version

This implements a new command 

        seqware --metadata

which returns all sorts of information about your metadata method. For webservice, this includes database stats, jdbc information, the version of the webservice, java environment, etc. 

The basic decider creates a warning if versions do not match.
The seqware check utility will fail if the client and webservice do not match
