Fix for find dialog in the relax controller window.

This is for bug #22816 (https://gna.org/bugs/?22816), the find functionality of the relax controller
window does not find text when using wxPython >= 2.9.

The find wxPython events are now bound to the find dialog rather than the relax controller window
LogCtrl element for displaying the relax messages. This works on all wxPython versions.

Fix for the find next bug in the relax controller window.

This is bug #22815 (https://gna.org/bugs/?22815), the failure of find next using F3 (or Ctrl-G on
Mac OS X) in the relax controller window if search text has already been set.

The fix was simple, as the required flags are in the self.find_data class object (an instance of
wx.FindReplaceData).

Improvements for selecting all text in the relax controller window.

Selecting text using the pop up menu or [Ctrl-A] now shifted the caret to line 1 before selecting
all text. This deactivates the following of the end of text, if active, as the text following
feature causes the text selection to be lost.

Complete redesign of the following of text in the relax controller window in the GUI.

The current design for some reason no longer worked very often, and there would be many situations
where the scrolling to follow the text output would stop and could never be recovered. Therefore
this feature has been redesigned.

In the LogCtrl element of the relax controller, which displays the relax output messages, the at_end
class boolean variable has been introduced. It defaults to True. The following events will turn it
off: Arrow keys, Home key, End key, Ctrl-Home key, Mouse button clicks, Mouse wheel scrolling,
Window thumbtrack scrolling (the side scrollbar), finding text, the pop up menu 'Go to start',
and Select all (menu or Ctrl-A). It will only be turned on in two cases: The pop up menu 'Go to
end', and if the caret is on the final line (caused by Ctrl-End, Mouse wheel scrolling, Page Down,
Down arrow, Window thumbtrack scrolling, etc.).

Three new methods have been introduced to handle certain events: capture_mouse() for mouse button
clicks, capture_mouse_wheel() for mouse wheel scrolling, and capture_scroll for window thumbtrack
scrolling.

Added extensive sectioning printouts to the dauvergne_protocol model-free auto-analysis.

The lib.text.section functions title() and subtitle() are now used to mark out all parts of the
auto-analysis. This will allow for a much better understanding of the log files produced by this
auto-analysis.

Changed the model-free single spin optimisation title printouts.

The specific_analyses.model_free.optimisation.spin_print() function has been deleted. It has
instead been replaced by a call to lib.text.sectioning.subtitle(). This is to match the grid search
setup title printouts and to differentiate these titles from those printed out by minfx being
underlined by '~' characters.

Alphabetical ordering of imports in the dauvergne_protocol model-free auto-analysis.

Added printouts to the determine_rnd() function of the dauvergne_protocol model-free auto-analysis.

This is for better user feedback in the log files as to what is happening. It may help in debugging
bug #22730 (https://gna.org/bugs/?22730): Model-free auto-analysis - relax stops and quits at the
polate step.

Added an additional check to determine_rnd() of the dauvergne_protocol model-free auto-analysis.

This is to try to catch bizarre situations such as bug #22730 (https://gna.org/bugs/?22730),
model-free auto-analysis - relax stops and quits at the polate step.

The additional check is that if the base model directory is not executable, a RelaxError is raised.

Added more checks to the determine_rnd() of the dauvergne_protocol model-free auto-analysis.

This is to try to catch bizarre situations such as bug #22730 (https://gna.org/bugs/?22730),
model-free auto-analysis - relax stops and quits at the polate step.

The following additional fatal conditions are now checked for: A file with the same name as the
base model directory already exists; The base model directory is not readable; The base model
directory is not writable. The last two could be caused by file system corruptions. In addition,
the presence of the base model directory is checked for using os.path.isdir() rather than catching
errors coming out of the os.listdir() function. These changes should make the analysis more robust
in the presence of 'strangeness'.
