Created a 100x100 version of the BMRB logo - this will be used for the export window.

The spin viewer window now uses graphics.fetch_icon() and shows the button text in the toolbar.

The showing of the toolbar text is simply to help the user understand the window quicker.

Added the mimetypes/text-x-texinfo.png Oxygen icons. This is for the relaxation data metadata button.

Improvements and fixes for the GUI pages of the bmrb user functions.

Merged the spectrum list GUI element into the base list element.

The base list element now has a delete() method, though I'm not sure if it is ever used. Now all
list GUI elements are derived from the Base_list class. This will simplify changing or improving
all of these elements.

Merged the relaxation data list GUI element with the base list element.

The base list element now has an Enable() method which simply enables or disables all buttons (as is
done in the relaxation data list). The button size is now specified as a (x, y) tuple. And the GUI
object can now be passed into the elements, as this is needed for the relaxation data metadata
window.

Large simplifications of the relaxation data metadata list GUI element by using the Base_list class.

Modified the molecule list GUI element to use the Base_list base class.

The base list GUI element has also been updated to support popup menus and to change the StaticBox
label upon updates. The base is_complete() method has also been added to always return True.

Small updates to the base list GUI element.

Created a GUI element for listing and setting the citations relevant for the analysis.

This will be used in the BMRB export window.
