MIRTH-2219: The channel ID is now selectable in the channel summary view. The actual component is a text field, but it's non-editable with no border so it looks like a regular label.
MIRTH-3184: Fixed HL7 deserialization bug when subcomponents were used in different places.
MIRTH-3358: Added ability to specify custom request headers on the Web Service Sender.
MIRTH-2179: Changed form URL encoding check from equals to starts with in the HTTP dispatcher, and improved client-side HTTP Sender validation so it no longer requires users to enter in a request body when form URL encoding is being used.
