[Elecraft] P3 button alterations (maybe not too late)

[inventor_sixty_one]

The power switch really isn't necessary; holding the QSY knob in could
perform the same function.
Most people will select for the P3 to come 'on' with the K3 anyway.
By freeing up the power switch position, you create five 'slots' (the former
power switch and the 4 PF buttons).
Then, you make those five positions into discrete half-height buttons, for a
total of 10 across the bottom of the display.
The 'menu' button next to the QSY knob stays as-is.
Very little additional board work or sheet metal changes would be needed,
and, the buttons and caps themselves are already
Elecraft stock parts, from the K1.  (Yes, I know they'd have to be silk
screened for this application.)
These ten new buttons would be labeled "160" "80" "40" et cetera; yielding
the much coveted dedicated band switches for each band,
and thus enabling full coverage direct band selection and allowing for
equally-wished-for band stacking registers.
This also eliminates the confusing choice of 8 unlabeled PF buttons, which
is what's there now.
