Adding description to for Xaw and NeXtaw

Added a description for Xaw and NeXtaw, because these are the two most important implementations of Athena. Xaw is the default, and NeXtaw has arguably the best appearance of Xaw implementations. I didn't add a description for the category of Athena itself, because some descriptions are more specific that they only apply to a scrollbar or menu. I intend to make improvements so more programs that use Xaw can have NeXtaw selected from make config. Here's a diff:
