Addition of repositotires of mediawiki that were analyzed

[dicortazar]

As similarly done in other Metrics Grimoire tools, it would be useful to have a list of mediawiki original URLs analyzed in the database.

This may help in two ways:

• Traceability of results, so third parties can check the original URL of the analysis
• Potential addition of more mediawiki servers in the same analysis, as CVSAnalY is able to produce a bigger dataset adding several repositories.

Thanks!
