Fixing instances of sort with sort-object

Fixes #535 - module using sort instead of sort-object causing unexpected behavior on powershell core/Linux.
Instead of only addressing the issue at hand, I looked for other instances of sort being used instead of sort-object for other modules within this repo and corrected those as well.  I think I got most of them, but feel free to raise another issue if you find another.  If the sort was in an example/help statement, or was inside the logic/process of the function, I replaced sort with sort-object.  In the one case where the sort was only applied to the output I removed the statement -- this way the function user can add the sort in their script and not have to sort output twice.  I changed a couple  select/where with select-object/where-object along the way as well just as I saw them.
