Re-added roundPointingOut style for eye and pupil

I originally removed this because you could generate the same style using
RoundedPointingIn(flip: .both). Re-added as it has tripped a number of
people up.

Fixed ios build

Fixed minor headlight bug

Replaced 'isFlipped' settings key with 'flip'

This provides more flexibility for shapes that support flipping, as
it supports horizontally, vertically and both

There was no point having two different flip settings.

Because of this, I've removed 'roundedPointingOut' because the same
shape can be generated using 'roundedPointingIn' and flipping both axes

Added 'surrounding bars' eye style

Added blade pupil style

Added 'orbits' pupil shape

Added new eye shape 'headlight'

Added new eye shape - dotDrag horizontal/vertical

Added grid pixel shape
