COMTRADE Export with fields that contain commas

[ritchiecarroll]

Some of the metadata being included for COMTRADE exports, such as the device name, can contain a comma.

When exporting to a COMTRADE CFG file, this throws off column count.

Commas should be removed when using metadata fields for source material.

This may be best fixed in the COMTRADE library itself as properties could auto-remove commas (or other problematic characters) in set functions for configuration metadata
