IPP on cal obs request form should default to 1.0

[nvolgenau]

In the form for submitting a request for photometric standard observation, the value for the IPP must be typed in. However, this value will probably always be 1.0 (i.e. no additional priority factor). A Cal-TOM user will rely on the TC and RR modes to get an urgent calibration scheduled.

The default value, 1.0, should be placed in the IPP field.
