splash screen patches (from <Someone>)

- Show splash on "Help - About" with all version information
- Show splash with news on startup (if show_splash is on of course).
I made another small patch to the splash screen. Because the greenish background colour always seemed a little odd to me, I decided
to make it transparent. Doing that, I found the following:
- The splash picture was a 24-bit bitmap, although it had less than 256 colours. That makes the size of the final executable about
200K larger than necessary. I changed it to a 256-colour bitmap. I also changed the background colour to the default tile background
colour, for consistency. The new bitmap is attached here. My excuses if the large file means a problem to anyone.
- In Microsoft's documentation (see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/bitmaps_2y9g.asp) is is
stated that on Windows 95/98 "TransparentBlt contains a memory leak that can exhaust system resources." It is recommended to use
different code to draw transparent bitmaps, to be precise: the alternative code that is already in nhapply_image_transparent(). I'm
almost convinced that this is the cause for Betabug B08008 reported bij <Someone>. Can anyone confirm he is using 95/98? I decided
for the easy way out and removed the code that uses TransparentBlt completely. I see not much reason to use it if it is a) buggy and
b) we have an alternative that works perfectly. This is attached as trans.patch.
- The rest of the patch only changes the BitBlt() in mhsplash.c to a nhapply_image_transparent().
