DaqScanDumbTest: A very bare-bones test of DaqAInScan() et al.
Add text mode fallback to ConfirmInfo() and TwoStateQuery().

Fix the two most useless and misguided functions in Daq toolbox.
They would otherwise fail on current Octave or Matlab in -nodesktop
mode.

-> Makes DaqFind not fall over if no Daq can be found.
DaqDeviceIndex(): Remove the "USB-1408FS untested" warning.

It is tested now and works at least on Linux, Windows-7 and
32-Bit OSX as far as my limited tests went.
DaqTest: Disable EEPROM read/write tests by default.

Having these on seems to be bat-shit crazy to me! Even
if there is only a small chance of bricking the device
this way, it is irresponsible default behaviour!

DaqTest gets about half-way through with the USB-1408FS,
so it is not fully adapted to test that device.
