Plugin assumes too much about file paths

[svenkle]

This plugin assumes too much about how a Sitecore site might be set up. For instance, if my prefix is mylittlepony and root is C:\inetpub\wwwroot it assumes the connection strings are located in C:\inetpub\wwwroot\mylittlepony.xconnect \App_Config\ConnectionStrings.config. This is quite often not the case as many of the Sitecore SIF installation steps are customizable.
