Add basic implementation of projectcount aggregation

The following databases to not get counts:
* advisorywiki
* bdwikimedia
* dkwikimedia
* donatewiki
* loginwiki
* mxwikimedia
* nycwikimedia
* nzwikimedia
* pa_uswikimedia
* rswikimedia
* sourceswiki
* uawikimedia
* votewiki
* wikimania2005wiki
* wikimania2006wiki
* wikimania2007wiki
* wikimania2008wiki
* wikimania2009wiki
* wikimania2010wiki
* wikimania2011wiki
* wikimania2012wiki
* wikimania2013wiki
* wikimania2014wiki

This is ok, as they are not in webstatscollector projectcounts files.
