Allow comments in LWM2M post operations

In the LWM2M post operations input field operations that will be sent to device can be edited. In the example window on the right there are comments that start with a "#" to describe the following line:

# Discover all resources of Object 3300, the generic sensor.

discover <objectId>

# Read maximum sensor value

read <objectId>/<objectInstanceId>/<resourceId>

Unfortunately comments are not allowed in the input field. This would be benefical as it would make the post operations more readable also for someone who does not have the all LWM2M object definitons in memory.
