All RelaxErrors are now coloured red if the status.text_colouring flag is set.

If the status.text_colouring flag is set, then the relax prompts will be coloured blue!

Fix for the initialisation of the Exec_info class for the prompt/script output.

The class was not being initialised at all! Thought the variables were class rather than instance
variables, so the problem was hidden.

Added a flag to the status singleton object to signal if text output can be coloured.

This is only activated when sys.stdout has not been changed. Unix redirection and pipes will need
to be handled later (http://mail.python.org/pipermail/python-list/2012-April/1291044.html).

Fix for the residue.create user function GUI front end along the same lines as the spin.create fn.

The unnamed molecules are now properly handled, and the gui_to_*() methods are now used for data
conversion.

Fix for the gui_to_int() function for when a text instead of an int is given by the user.

Clean up of the Create_page.on_execute() method.

The gui_to_*() functions are now being used for the spin information.

Removal of a debugging print out.

Copyright updates.

Bug fix for the spin.create user function GUI interface for when molecules or residues are not named.

Unnamed molecules are now properly handled in the GUI page, and the residue name of None is properly
converted into a NoneType prior to executing the back end.
