Wrong link "Edit this page" when using Multisite #80
Description
When we are using the multisite setup of Grav, especially the one with subdirectories, the link to the Git resource for editing the page is wrong.
We expect to have:
http://mygit/myproject/blob/master/pages/01.basic/01.sometopic//docs.md
But we have instead:
http://mygit/myproject/blob/master/sites/mysite/pages/01.basic/01.sometopic//docs.md
Where http://mygit/myproject/ is the root of the git project (on github, gitlab of any other system), the page is /basic/sometopic and the site in multisite setup is in the mysite directory. It means the doc is accessible via http://mydoc/mysite/basic/sometopic.
The sites/mysite is in the way. Learn2 just imagine that the root folder of the doc is directly in pages folder when it is in pages/sites/mysite.
