PowerShellProvider was moved to separate project

provider to enable building relative paths from any FileSystem location
Merge in other changes and correct tests

Corrected tests to handle new (proper) relative path formats.
Extended relative path testing

Added test for relative path to itself
Changed to platform neutral relative paths
