fix issue with WE+ bit becoming unset, fix pagefault:not-mapped-in logic
- The WE+ (page write enable) bit was becoming unset when the Page Status bits were being set.
A stupid mistake in an AND expression was unsetting the write-enable, thus making S4TEST 12,2 and 12,3 fail spectacularly.
- Pagefaults were not being generated correctly for pages which were not mapped in. Even Supervisor code accessing unmapped pages should get a PF.
