Lists number of files in all lists and folders for the given site

Author: Albert-Jan Schot

List all Lists, the folders and sub folders in a given site, and output the item count. Each folder is processed recursively. By default only non hidden document libraries are processed. As specified with the filter $false -eq $list.Hidden -and $list.BaseTemplate -eq "101". The output is a CSV that contains the itemcount for each list and folder found in the specified site collection.
