Fix P-733 AutoZero call

[zacsimile]

...and add some spaces to error messages for nicer formatting.

There was a mismatch between the function call automatically generated by LabView and the actual PI call.

Generated call:

True call:

Fix:

Note that, once fixed, the pdLowVoltageArray input had to have constant values filled in (in this case I put -5 in entries 0-4), despite the fact that we explicitly tell the API to ignore this array in pbUseDefaultArray. If you just right click and add a constant without then manually updating the first few entries (at least enough to account for the number of axes you plan to AutoZero), the call will still fail even with a 1 in pbUseDefaultArray.
