Moved WeeGUI to HGR2 in memory

Trying to co-exist with ProDOS, BASIC.SYSTEM and Applesoft at the top of memory was giving me too many gray hairs. WeeGUI apps shouldn’t need the HGR2 page, so we’re going to live there from now on.

-WeeGUI is 6k in size, and lives at the top of main memory, right under ProDOS. For an experimental version that lives primarily in the auxiliary memory bank, see Appendix A.
+WeeGUI is about 7k in size, and lives on top of the second hires page. The assumption is that, if you're making an 80-column-text-based GUI program, you don't _also_ need fancy hi-res page flipping animations. For an experimental version that lives primarily in the auxiliary memory bank, see Appendix A.
