task: let the user turn lube on/off at all times
axis: coolant and spindle control are allowed at all times

Spindle increase/decrease has always been allowed by Task while running
a program, it never made sense for Axis to disallow it.

Coolant (flood & mist, on & off) used to be allowed by Task only in
certain situations (and not while running a gcode program), but that's
no longer the case, so enable Axis control over coolant unconditionally.
