Help menu for SheepShaver in OS X

These changes implement a SAMPLE Help menu in SheepShaver for OS X,
when built with Xcode under OS X 10.6.

To implement the Help system, open the xcodeproj file, ctrl-click on
SheepShaver, and add a New Group, named Resources.

Ctrl-click on Resources, choose Add->Existing Files and navigate to the
English.lproj folder, and Add it. In the dialog, switch from the
default setting to Create Folder References…

Clean and build.

Remember, these menu entries are only SAMPLES of what can be done. I
hope someone finds these useful.
