Add a codebase/repository WebCrawler and build an crawled documentation index in SCP

[totto]

The idea is to find and crawl blogs and presentations and other sources and add them to the SCP documentation index for a repo/group/organization - all info/documentation/++ in one place, always updated and close to the source

Typically a web crawler which crawls the web after pages containing e.g. the github repository name?

We currently crawl document-files on github and document links in poms... we'll work towards indexing and thus enable good search functionality and probably variants of hot/instant linking in scp at some point in time :)
