refs #2465: Starting the Insight plugin (in-site analytics)

This is the code I wrote about a year ago :)

There are several things that will be changed / removed but it's still good to have it in SVN - that's why I commit it like this.

git-svn-id: http://dev.piwik.org/svn/trunk@7223 59fd770c-687e-43c8-a1e3-f5a4ff64c105
