Fix T67067: Wrong rotation input values when using shortcuts on keyboard like rx720.

This allows to type in numinput 720 and indeed get a rotation of 720�, not 0�...

This patch basically applies 'big rotations' in steps < 180�, such that
compatible rotation works as expected. This implies resetting current
rotation to initial one first, otherwise we'd end up applying much more
turns than expected when that code is called more than once.

It also makes things somewhat slower for big rotations (millions of degrees),
Hence we clamp to 1000 turns max.

And since that's a case that cannot happen with regular tool/widget-driven rotation,
it's only enabled when numinput is used for now.
