[Mono-winforms-list] HelpProvider Class

[Phil Turnbull]

Hi all,
Ive implemented the HelpProvider and related classes :)

At the moment the Help class is a stub as i believe the Theme class needs a
new method such as 'DrawPopup'

Also, i was planning on implementing the Screen class if this is not being
worked on. Whats the status on the class?
