e9aaa5bbdf Factors out the page-mapping function. 
For one less potential source of failure.

ecb26e3281 Corrections: slot_C3_rom_ works the other way around; 80STORE doesn't affect most of RAM but does always affect the text screen. 
Also factored out `set_zero_page_paging` for consistency.

bc2afe69e1 Accepting that memory mapping on a IIe is more complicated than I anticiapted, introduces mapping for all pages. 
Also picks a name for the Unenhanced Apple IIe ROM.
