load_file for ICP data doesn't work if temperature isn't included in the data

[js54434]

I'm trying to load some BT9 files, but I get this error:

data1.load_file(filename, mode='ICP')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/johnschneeloch/anaconda/lib/python2.7/site-packages/neutronpy/core.py", line 373, in load_file
    output[key] = args[headers.index(value)]
ValueError: 'Tact' is not in list

The data file happens not to have a temperature column, which I think is what's causing the error.

This issue will be covered in the upcoming Data class rewrite that is currently in progress.
