Update QLab installer.

--CAR and TAO
Fixed bit rot in Anritsu driver; case of Write was changed.
Allow switch marker state to take an instrument object or a string (more compatible with our way of doing things)
It's OK for .seq file to have a different path on AWG and host computer.  Emit a warning because it is admittedly a bit weird.
Add a new pulse type for RIP pulses.
Helpful comments as someone saw fit to change units in some (but not all) places to GHz.
Yet another random case change for no reason, and make get/set units consistent with new "standard" of GHz.
Add error check function so errors like "out of range because someone saw fit to randomly change units" don't get lost down the bit bucket.  I'd suggest adding code like         if ismethod(obj,'check_errors') obj.check_errors(); end to the setAll meta-setter, but I don't know the code base well enough to know if that would cause side effects.
Make calibration failure a warning rather than error
Measurement filters are now digitizer specific.
