BioWSR Code

* Minor changes on RDF/SQL database schema.
* Added more functionality to wsrcore (still untested).
Last bits related to service updates must be added before
we link the core to the web service registry layer.

* Deleting stupid lines

* Due problems with redland library, 'SeviceModule0 package has been commented
temporarily within WSRendpoint.rb
* Due a conflicts with package file, 'cgi.rb' has been renamed to 'mycgi.rb'
* Added redirect option within printhttp.rb

* Added support for multiples URIs which are pointing to the same resource,
so the services are tracked even when the physical RDF is moved.

* Still not functional code, but at least another step.
- addURL and updateURL logic is in place.

* SQL schema has been (almost) finished, so it has the needed tables.
* WSRCore initialization bits have been introduced (creating the schema, writing metadata, and so...).

* Metadata directory has been moved inside lib directory.

* SQL schema has been updated and improved.

* Fetch and validate functionality has been expanded and moved to an internal function
which is going to be reused on insertion, updates and so.

* Added test directory, composed by small tests related to libraries
used in BioWSR.
* Added wsrcore, the seed of the full system. Validation should work.
* Some code in ServicesModule has migrated to wsrcore.
