make flash-local?

[Jeff Rush]

While there is a "flash-qemu-local" make target in MokoMakefile, there doesn't 
seem to be a non-QEMU flash target.  Or am I overlooking an easy, one-command 
way of updating the device?  I can do it the long way with dfu-util but hoped 
there was a simple way that would flash the latest locally-built image as well.
