Created the _Exit class so that the prompt GUI element exit fns behave the same as in prompt mode.

The relax prompt GUI element now overrides the exiting functions 'exit', 'q', 'quit', 'bye'.

These now correspond to the relax GUI exit_gui() method. The IO streams are also restored prior to
printing out the citations, so they are printed in all cases.

Changed the colour scheme of the relax prompt GUI element to mimic gvim colours.

Created the relax prompt GUI element.

Temporarily reverted r11578.
