was missing an rts on update_palette
this happened to fall through to keycheck
which if timing was wrong would dutifully process the viewport
change and return to update_palette's caller
which in turn was -not- expecting to reset the outer loop

Runtime detection of XE-style extended memory
...
Uses the "big multiplication table" in 64KB of extended memory if
bank switching appears to work, otherwise uses the table of squares
lookups.
Initial view clocks in at 13.133 ms/px for the XE version and still
14.211 ms/px for the 400/800/XL version.
Tested in emulator with 130XE and XL+Ultimate 1MB upgrade configs,
and base implementation on the 800XL emulator.
