#219 Added instruction page to settings dialog

[Brandon Taylor]

Created a preliminary instruction page for the VICE settings dialog. Right now it looks quite bland. If anyone can help with making it look better, don't hesitate to add your own enhancements.

First off, this is not a patch. The easiest way to create a patch is creating a diff while being in the vice dir:

svn diff > my-patch.diff

That'll create a diff which makes it a little more understandable for us. It'll show the differences between what you did and trunk.

Your patch will only work for C64-based emulators, not for VIC-20, PET, CBM-II, Plus4, etcetera, since you mention VICII and SID. It also doesn't really add any useful information, I think most users can figure out the 'video' or 'sound' main tree nodes.

Your patch also doesn't adhere to our code style: you use tabs while we require spaces for indentation, 4 spaces per level. This is a detail that can be fixed.

Finally, using a GtkLabel isn't the way to go about presenting formatted text, something like a GtkTextView allows for proper formatting, see for example https://sourceforge.net/p/vice-emu/code/HEAD/tree/trunk/vice/src/arch/gtk3/widgets/hvscstilwidget.c

So, I'll reject this patch. The idea is okay, the execution not so much.
