Renamed some channels

This release contains optimizations such as:

• changed channel names according to openHAB standards (camel style)
• some channels are now delivered as QuantityType channels
• some improvements in speed, eg using openHAB routines where available
  Since some channel fields changed you may notice that some Items don't work anymore. Delete them and create a new Item (with the same name) and reassign it to the corresponding channel.
