#136: Add error handling to message writing process

Browse source 
In the updated version of msgwriter.go, an additional error handling process has been included. If an error is detected when creating a new part in the message writer, this error is stored and prevents executing the writeBody function. This fixes nil pointer dereference in `mw.writeBody` if an error occured previously
