Removed the last reference to the eliminated Exec_info prompt object.

Clean up of the prompt intro strings for the auto-generated user functions.

The prompt intro strings are now created for the auto-generated user functions.

Missing import of the status object.

Absorbed the Exec_info prompt object into the relax status singleton and eliminated it.

The prompt strings are now prompt.base_class module variables, and the current ones are stored in
the status object. The user function intro flag is now stored in status.prompt_intro. The
prompt_colour_on() and prompt_colour_off() methods are now methods of the interpreter class. Now
that the Exec_info class no longer exists, the Basic_class class has also no purpose and has been
eliminated.

The prompt help system now uses bold text for the title line and all subtitles.

The subtitle underlines are now not used, but the ability to underline is retained.

The relax prompt help system is now being passed through pydoc.pager to page the text.

This system will be used by the auto-generated user functions.

The documentation for the auto-generated user functions is now being created.

This is stored in the __relax_help__ string, and mimics the old system, reusing many of the base
functions. All the user function data required for the prompt interface is now being passed in to
the object.

Renamed the private _args variable to the non-private kargs.

The user function object now has a __repr__ method to give better feedback to the user.
