update scripts acordingly

configs/test/SysPaths.py:
    new syspaths from nate, this one allows you to set script, binary, and disk paths like
    system.dir = 'aouaou' in your script
configs/test/fs.py:
    update for system mem_mode
    Put small checkpoint example
    Make clock 1THz

src/sim/system.cc:
src/sim/system.hh:
    update for system mem_mode
src/dev/io_device.cc:
    Use time returned from sendAtomic to delay
