Title: rename MPIExecLaunchers to MPILaunchers

MPIExec is unwieldy, and unnecessarily specific when they can be configured to use mpirun, aprun, etc.

This means you can now start an MPI cluster with just:

$> ipcluster start --engines=MPI

old names still work, logging deprecation warnings and pointing to the new names.
