//FUNCTIONALITY:
//This popup menu functions IDENTICALLY to Windows95's methodology. You can use the arrow keys, or the
//mouse in two methods. The first method is where you release the mouse button before
//moving the cursor inside the popup menu, which makes it persistant (it won't go away until you click again),
//or non-persistant, where you release the button inside the menu after your initial click (non-persistant).
//IMPORTANT NOTE:
//Linda Currie, the main user of the editor dislikes the non-persistant functionality, however, it is still
//supported. Just remove the commented line of code (search for UNCOMMENT), and it's fixed -- it is
//currently disabled.

InitPopUpMenu
---------------
Creates the popup menu, then takes control of the i/o
effectively turning the popup into a modal system (forcing the
user to make a selection or cancel before doing anything else.
There are two modes of operation as soon as the user presses the mouse
on a popup menu activation button.
1) The user releases the mouse before moving the cursor onto
the popup region. The popup menu will end as soon as the
user presses the mouse button. If the cursor is out of the
popup region, then it returns 0.
2) The user holds the mouse while moving the cursor onto the
popup region. The popup menu will end as soon as the user
releases the mouse button. If the cursor is out of the popup
region, then it returns 0.
Returns 0 if nothing in menu was selected, else
returns the menu entry number starting from 1.
