relax SVN archive

Modified the data checking at the start of automatic_protocol_controller().

Deleted __do_layout() and __set_properties().

These were not being used and contained code not belonging to the automatic Rx analysis frames.

Switched to using the blue 'add' icon.

Changed the colour of the icon to match relax' blues.

Modified refresh_peak_list_display() to update the relaxation times as well.

Rewrote refresh_r1_1() into the new empty_list() method.

This simply resets the relax data store variables and calls refresh_peak_list_display().

Fix for peak_list_add_action().

The check for the list being full was not working.

Complete rewrite of the add_r1_1() method, now called peak_list_add_action().

This includes:
- The proper support for multiple file selections.
- Checks for too many peak lists.
- A new method called count_peak_lists() added.
- The refresh_peak_list_display() method written to update the GUI element at any time.

Updated the multi_openfile() function.

The args were turned into keyword args, the function comments converted to a docstring, many comments
added, whitespace fixes, and dialog.GetPaths() is now used to return a list of files.

Created the gui_bieri.message.error_message() function for displaying general errors.
