Provide a way to blacklist a set of wikis for crosswiki search

The list of sister projects returned by SiteMatrix is not always
interesting to be added in the crossproject search sidebar.
This patch adds the possibility to fine-tune this list by providing a
set of interwiki prefixes to blacklist.

This affects only SiteMatrix implementation.
