Replaced command that pruned non-setup BW imagess because combining positive and negative filters with `docker prune` seems to be broken in Docker Desktop.

Added switch to purge function to allow all BW images to be purged (dont exclude setup image) during uninstall.
Added verbiage to clarify purge behavior.
