Test loading a thuban session from a file

The tests in this file (test_load.py) are always be the tests for the
current version of the thuban file format. Tests for older versions can
be found in the version specific test modules, e.g. test_load_0_2 for
files created by Thuban 0.2.

Maintenance of the test cases:

When during a development period the file format is changed with respect
to the last released version for the first, the tests here should be
copied to the version specific test file. The round-trip tests which
save the session again and compare the XML files should not be copied
over as they only make sense here to make sure th that the files checked
here are actually ones that may have been written by the current thuban
version.
