Update all Processing sketches to use the OPC.pde version from
grid24x8z_clouds that uses background/async socket management, and
doesn't grid to a halt every time the server drops out

New READMEs for the examples, and update everything for the new layoutful naming convention.

This lets us disable the Nagle algorithm, and have finer control over error handling

I originally had this in here as a workaround because sometimes fcserver would fill up its USB queue, but this increases lag a lot. Much better without, and if fcserver acts up again I should just fix it :P
