Renamed the intro.Intro_text class to info.Info_box.

This is used for introduction strings, but can be used at any point in relax as well.

All dialogs (the relax controller and about dialogs) are now being destroyed by exit_gui().

This allows the program to exit!

Cleaned up the exit_gui() method (previously called exitGUI()).

A docstring and comments have been added. The exit dialog text has been re-written. And the call
to sys.exit() has been replaced by a call to self.Destroy() to exit the frame (to exit properly,
some other GUI elements need to be destroyed too, though these are not clear yet).

Shifted the MainLoop() call to be outside the wx.App initialisation.

This was a strange place to have it, in the OnInit() method! This should prevent future issues.

Clean up and expansion of the question() dialog box showing method.

A docstring and comments have been added. And the arg default added to allow yes or no to be the
default button.

A close box is added to the relaxGUI main window as requested by Edward d'Auvergne.

The original post is https://mail.gna.org/public/relax-devel/2010-02/msg00025.html. This patch
corresponds to file #7925 (http://gna.org/support/download.php?file_id=7925).

A keyword for window decoration was added.

The about windows now stay above all others!

Variable name fix.

Sent some initialisations into __init__() to occur before the Bind() calls.

This will fix some intermittent errors.

The cursor type now changes to a hand when hovering above the link in the relax about widget :)

This involves binding all mouse actions (wx.EVT_MOUSE_EVENTS) to the cursor_style() method.
