Initial implementation of the common BAboutWindow class. Of course I just

realized that calling it a window may not be strictly correct since it isn't a
decendent of BWindow, but just uses a BAlert. Oh well, it can be changed if
need be.

I'm also checking in the first use of it, in ShowImage. Since ShowImage can
still be compiled for R5 I've added a #ifdef around the new BAboutWindow
related code.

I'm open for suggestions for the interface for this class, well mostly the
constructor. I'm not a big fan of having to specify the number of authors.

For now I'm making the header private, but I don't think it would be a big deal
to expose it publically.
