Werk #2489: cmciii_lcp_water: New check replacing cmciii_lcp_waterin/out, support for newer devices

This is a more robust reimplementation of the Water-In/Out checks that also works for newer firmware and has been converted to the new temperature handling and thus also allows for custom levels (if you want to override those set in the device itself).

Note: You need to reinventorize the hosts in order to use the new check.
