File Dialog Class (replace common dialog control with this lightweight class)

Replaces Microsoft's common dialog control file dialog features. Uses same interface to call the FileOpen and FileSave dialogs including multiselection support. Instead of making a more versatile control with print dialogs, color dialogs, and hooking, I decided to make a very lightweight one since the CommonControl Print and Color Dialogs are essentially useless. I could have added hooking functionality, but that would involve including a standard module as well. The only major benefit of hooking is the ability to center the dialog. However, with this code, as long as you specify the form's handle, it will position the dialog to the upper left of the form This is a direct replacement to the Microsoft CommonDialog control and will involve very little Change in coding to implement.
