Python 3 integer division to float fix for the frame order analysis.

Python 3 bug fix for the frame order analysis - another int division problem.

Python 3 fixes - eliminated all usage of the dictionary has_key() calls as they are no longer present.

Python 2 and 3 support in the generic_fns.relax_data module using 2to3.

One print call was fixed after running 2to3.

Python 3 bug fix for the Structure.test_read_pdb_mol_2_model_scientific system tests.

This is again an integer division problem returning a float.

Python 3 fix for the test_write_protein_sequence() unit test.

This is again a string verses byte verses unicode problem.

Python 3 fix for the user function docstring creation in the prompt UI mode.

Again this is the problem of a division now returning a float rather than an int.

Python 3 bug fix for the N-state model target function setup.

The num_tensors variable needs to be an integer, but the Python 3 division will create a float type.

Python 3 fix for the reading of text from a bz2 file.

In Python 3, the readlines() function was returning a list of bytes types, not a list of strings.
The relax_io.extract_data() function now detects this and converts to string when possible.

Python 3 fix for the results.read user function matching that of state.load at r17666.
