During the GUI tests from the GUI, the relax controller is now modal.

This is to stop users from doing silly things!

Shifted the code of r15803 from the test suite into the GUI method for running the test suite.

The relax controller now stays on top of all windows when the GUI tests are being run.

This improves the running of the GUI tests in GUI mode on Mac OS X and MS Windows.

Added the Bruker PDC (or now DC) to the http://www.nmr-relax.com/links.html webpage.

This is in response to Klaus-Peter Neidig's (neidig att bruker dott de) message at
https://mail.gna.org/public/relax-users/2012-04/msg00011.html (Message-id:
<4F7AE13B.6010309@...>).

The Mf.test_write_results system test now works with the newer Python 2.7.3 version.

The final_results_trunc_1.3_new.bz2 file was updated to be a results file rather than save state,
and the system test itself now checks the Python version and then loads the correct results file for
that version.

Added a new version of the truncated OMP results relax state file.

From Python version 2.7.3 (and the equivalent 3.x versions), the XML toprettyxml() output has been
changed to not wrap the value in newline characters! See line 258 of the Python change log at
http://hg.python.org/cpython/file/d46c1973d3c4/Misc/NEWS#l276. This change affects one of the relax
system tests.

Fix for the setuptools RelaxError for when the extension is unknown.

Pyreadline download link fix on the http://www.nmr-relax.com/download.html webpage.

Docstring completion for the ansi.enable_control_chars() function.

ANSI control characters are now suppressed on MS Windows.

The characters are useless in both the PowerShell and cmd. Therefore the
ansi.enable_control_chars() helper function has been created to replace the sys.std*.isatty() calls
throughout relax.
