Changed the text of the main gauge in the relax controller.

The model-free and relaxation curve-fitting gauges are now differently named.

This should allow the MC simulation gauges to update correctly, as the rx fitting one was being
overwritten by the model-free one.

RelaxWarnings are now coloured 'orange red' in the log control of the relax controller.

The Monte Carlo simulation number is now stored in the auto-analysis part of the status object.

This is only when an auto-analysis is running.

The current analysis is stored by name in the status singleton when the exec_lock is on.

The relax prompt is now coloured blue in the relax controller log element.

The STDOUT and STDERR streams are segregated in the LogCtrl and STDERR messages coloured red.

The relax controller log window can now distinguish between STDOUT and STDERR messages.

STDOUT and STDERR are now being sent to separate instances of Redirect_text, and added to the log
queue with a flag specifying which is which.

The relax controller and auto-analysis threads are now active in debugging mode.

The Redirect_text.write() method now sends the text to sys.__stdout__.write() prior to any other
actions so that all debugging messages are sent minimally to the terminal. This allows debugging
of the GUI and threads with them being active.

Redirect_text is now placing all messages onto a log queue and the LogCtrl is reading from this queue.

The log_queue Queue object is now used to store messages so that not every write() event to STDOUT
and STDERR results in the relax controller log window updating. This allows the controller and the
GUI to remain responsive as masses of messages are produced.
