relax SVN archive

Missing imports of the font module.

All buttons now have their fonts set.

The about relax DC elements are now properly centred.

The border should not have been added to the x extent.

The about relax dialog is now resized dependent on the extent of the text.

The wx.lib.wordwrap module is now used for wrapping the text in the about dialogs.

Fixes for the results viewer window updating on Mac OS X.

The EVT_SHOW event was not being triggered by the frame's Show() method?!?!

Shifted the font initialisation to the very start of the GUI launching.

Set the font on the 'Execute relax' button.

The results files lists are only updated if the files are not already there.

Complete redesign of the relax controller!

The new features include:
A dynamically updated analysis specific status update.
Analysis specific GUI elements, dynamically hidden or shown.
A display of the current analysis and current data pipe.
Correct updating of the gauges in all analyses.
Separation of the text redirection and the progress updating.
Text scroll back limited by default to 100000 lines.
Text scroll back cleared as a user would expect with removal of lines from the start.
Cleaner layout of all elements.
