Docstring fix for test_bug_15050().

Shifted the bug #15050 system test script to the correct directory.

Added a system test for catching bug #15050 (https://gna.org/bugs/index.php?15050).

This bug was submitted by Tiago Pais (https://gna.org/users/tpais).

align_tensor.display() now prints the magnetic susceptibility tensor.

This only occurs if the field strength and temperature are given.

Fix for bug #14941 (https://gna.org/bugs/index.php?14941).

This was reported by Mikaela Stewart (mikaela dot stewart att gmail dot com).

The problem was that the global_flag variable was not being passed into the analysis specific API
duplicate_data() method so that only the first spin's data was being copied, all other spin
containers were empty.

Added a catch for bug #14941 (https://gna.org/bugs/index.php?14941) to the relax system tests.

This uses truncated data (first 2 residues), also randomised, to reproduce the bug.

Fixes for the overfit_deselect() methods.

The spin_id was not being returned by the spin_loop().

Added the select_model_calc modules.

This module is a dialog whereby users can choose the model-free model.

Added the filedialog and message modules.

These are new files which replace functions within easygui.py.

Fix for the call to spin.name(). The keyword arg must be specified as 'name'!
