Remove unnecessary files

These files came from the E-vident repository migration. Shouldn't be
needed in Emperor itself.
Add changes to setup.py for the deleted resources
Fix bug reported in #66

The copy_support_files function was not accounting for filepaths that
contain spaces or other invalid characters, hence when trying to run
make_emperor.py and setting the output path to something like
"/Users/jappleseed/data/oct 12/" would fail because of the "oct 12"
component in the path.

A new test has been added to test_util.py.

Fix #66
Change GUI display to show sorted values only

Elements showing lists in the GUI, are sorted alpha or numerically.

Fixes #56.
