Shifted code from relax_gui.state_load() to the new Analysis_controller.load_from_store().

This is to place all analysis code in the Analysis_controller class.

Added a link to NESSY (http://home.gna.org/nessy) to the links webpage (http://www.nmr-relax.com/links.html).

Added the NESSY icon from http://home.gna.org/nessy/pics/NESSY.png.

Shifted all of the analysis specific code into the new Analysis_controller class.

A few new methods have been created to abstract the page objects and other analysis specific
structures.

Created a new class Analysis_controller in gui.analyses for handling all aspects of analyses.

Removed the unused and very old code of the analyses.project module.

No PyMOL macro is created as no PDB has been input.

Fixed a typo in the grace file name of the NOE analysis GUI test.

Fix for the threaded NOE analysis execution - the data_index arg to __init__() was missing.

The auto NOE analysis page has been redesigned around the new results viewer window design.
