Support entering DPT translation information in monitor mode

Group monitoring allows executing read/write commands while monitoring. 
Part 1: this commit adds parsing of those commands from System.in, to 
use the DPT information in subsequent monitor events.
Load/save monitor datapoint information for DPT translation from/to file

Part 2: in group-monitor mode, remember datapoint information between 
tool invocations by writing a datapoint model to file on exiting process 
communication.
Recognize name aliases for common DPT numbers

Part 3: in group-monitor mode, recognize the same common DPTs via their 
name aliases as for normal read/writes.
Execute read/write commands in group-monitor mode

Part 4: in group-monitor mode, execute the read/write commands that are
read from System.in.
