spylab.py throws AttributeError: 'dict' object has no attribute 'has_key'

Using the Python3 branch, and running the following code, I get the above Error.

from spectral import *
img = spectral.open_image('avng.jpl.nasa.gov/AVNG_2015_data_distribution/L2/ang20150422t163638_rfl_v1e/ang20150422t163638_corr_v1e_img.hdr')
print(img)
# Data Source:   '././ang20150422t163638_corr_v1e_img'
#   # Rows:           4031

#   # Bands:           432

view = imshow(img, (29, 19, 9))
print(view)

AttributeError: 'dict' object has no attribute 'has_key'

This is due to has_key being removed in Python 3 see https://docs.python.org/3.1/whatsnew/3.0.html#builtins
