Ethan Atkins dc4f705500 Add support to rebuild a '~' task by pressing 'r'
Sometimes a user may want to rerun their task even if the source files
haven't changed. Presently this is a little annoying because you have to
hit enter to stop the build and then up arrow or <ctrl+r> plus enter to
rebuild. It's more convenient to just be able to press the 'r' key to
re-run the task.

To implement this, I had to make the watch task set up a jline terminal
so that System.in would be character buffered instead of line buffered.
Furthermore, I took advantage of the NonBlockingInputStream
implementation provided by jline to wrap System.in. This was necessary
because even with the jline terminal, System.in.available doesn't return
> 0 until a newline character is entered. Instead, the
NonBlockingInputStream does provide a peek api with a timeout that will
return the next unread key off of System.in if there is one available.
This can be use to proxy available in the WrappedNonBlockingInputStream.

To ensure maximum user flexibility, I also update the watchHandleInput Key to
take an InputStream and return an Action. This setting will now receive
the wrapped System.in, which will allow the user to create their own
keybindings for watch actions without needing to use jline themselves.

Future work might make it more straightforward to go back to a line
buffered input if that is what the user desires.
