GP Sculpt: Experimenting to make sculpt operator non-modal

Sometimes the modal nature of this operator made it cumbersome to operate.
This commit tries to make this better by making changes to the operator + keymap
so that:

* EKEY + LMB-drag (just like for drawing) = Do a single sculpt stroke
(i.e. it starts immediately, and ends as soon as the stroke ends)

* CTRL + EKEY = Enter Sculpt Mode (as before). Can do multiple strokes this way
without holding down any keys.

* DKEY + EKEY -> Sculpt = Enter Sculpt Mode (as before)


I'm still on the fence about the Ctrl+EKEY one. Perhaps it's too much of a hassle,
and we just drop this one?

GP Sculpt: Assorted tweaks to investigate problems with Twist brush

* Some of the problems stem from inaccuracies/noise introduced by the 2D -> 3D
conversion that takes place. For some reason, some verts randomly get offsets
when reprojecting everything.

* Twist brush strength isn't 1.0 degree anymore

* It still doesn't work well though :(

GPencil: Initialise default values for before/after onionskin colours

Newly created layers will now get a pair of default values for the before and after
onion skinning colours. These are currently hardcoded to a green and blue colour
(respectively). Also, "use colours" toggle will be enabled by default, so that these
colours will be applied as soon as you show the onionskins.

Revert last commit where attempt of keeping autohide state was made

attempt to reduce flickering with autohide by memorizing which faces were not deleted in one autohide pass and keeping them, side effect: when playing the sim backwards autohiding wont work properly until reset to start frame again.
