MIRTH-2504: Fixed form layout in the Web Service Sender so that the minimum height for the SOAP Envelope text area is set to what it used to be.
MIRTH-3302: Modified the HttpConfiguration interface so that it can now dynamically inject source map variables per request.
Fixed the part where this was broken.

In JdbcDao, updateSourceResponse has been renamed to updateSendAttempts and now updates the sent attempts, send date, and response date. Both the source and destination connectors use this to update their send attempts now instead of bootstrapping it onto updateStatus.
Issue: MIRTH-3288
Fixed "Remove Content on Completion" not working if the message was not sent to any destinations. If there was only a source message, the message was always being marked as not completed. However there are valid cases when the message can be complete even if there is only a source message, specifically if the message was filtered on the source or if the message was not sent to any destinations.
Issue: MIRTH-3361
MIRTH-1983, MIRTH-2289: Added a socket timeout property to the Web Service Sender. This is used not only for actual dispatching but also for the Get Operations connector service.
