[Ovmsdev] Console output batched up while command is run #32

This phenomenon is a consequence of the Mongoose behavior of buffering
all the data rather than sending immediately. We talked about some
approaches for an option to control that behavior, but I did not
implement any at the time since we were running with an unmodified
Mongoose at that point and we were not hitting memory crashes after
the adjustments we had made with tasks and stacks.
Subsequently we did decide to maintain some modifications to Mongoose,
so perhaps now I should implement an option for immediate sending.
