Media Player mainfrm.h

This module contains all event handling for menus in the Media Player.
The implementation is WTL (Windows Template Library) based.
The main menu is:
File Edit View Play Options Help
File opens/closes movies and has print features.
Edit has copy/paste features.
View has spatial controls, such as scaling, and tool and status bars and a properties dialogue box.
Play has temporal controls, such as play speed and pause.
Options controls details such as Audio and Video on/off.
Help is just an about box.
Right clicking brings up a context menu with edit and view items.
A tool bar exposes the most common menu items as buttons.
Hotkeys (accelerators) are mapped to most menu items.
A .RC file is used to edit the menus using the resource editor in visual studio.
Dialogue boxes are each handled by a different .h.  ie props.h for properties.
Mainfrm.h does some minor dialogue boxes directly, such as the file selector and alert boxes for errors.
