Define a keyboard scan code for PrintScreen. There is no real scan code for the PrintScreen key under DOS, but it is convenient to be able to bind it as a screenshot key. Define a "fake" scancode (126) to represent PrintScreen so that it can be represented as a key binding in configuration files. Also add some comments/notes to the scantokey[] lookup table. This fixes #369.

+// Mapping from DOS keyboard scan code to internal key code (as defined
+// in doomkey.h). I think I (fraggle) reused this from somewhere else
+// but I can't find where. Anyway, notes:
+// * KEY_PAUSE is wrong - it's in the KEY_NUMLOCK spot. This shouldn't
+// matter in terms of Vanilla compatibility because neither of
+// those were valid for key bindings.
+// * There is no proper scan code for PrintScreen (on DOS machines it
+// sends an interrupt). So I added a fake scan code of 126 for it.
+// The presence of this is important so we can bind PrintScreen as
+// a screenshot key.
