Merge branch '28' into custom-manipulators

Initial bisect widget

Uses view 3d manipulator option

Add support for delayed removal

This is needed so manipulators can tag themselves for removal
without causing problems from freeing data within a callback.

Also use properties within the dial manipulator and fix an error where
removing a wmManipulatorGroupType didn't remove its keymap.

Fix error in Cameraview when zoom

The problem was related to object scale

allow triggering in external mode too

Fix segment fault if palette is missing

In some weird situations the palette can be removed.

We could consider to remove all strokes in this situation, but need further analysis. We keep the pointer checking as initial solution.

Added point to origin and LMB click

Implement a hash to relink palettes

Add a hash system when relink the colors to strokes to avoid the loop of all colors for each stroke.

Could use a hash for palettes, but as usually the number of palettes is very low, the speed up using hash doesn't worth the code complexity.

automated some UI selections

now smoke domains set volume cache automatically, liquid domains set surface cache automatically

New icon for Outliner and changes in Stroke Paint icon

The outliner icon for grease pencil must be gray to keep UI consistency.

Changed the stroke paint icon to make more visible.

Icon design credits go to Matias Mendiola

Dial manipulator didn't have a modal callback

Until 3d-viewport manipulators change functionality we need to it
working how it already is.

So add modal operator which is called from draw when there are no
properties applied to the manipulator.

This will be needed to have a general rotation manipulator.

Fix error with object scale and stroke thickness

With new calculation of previous commit for stroke thickness the scale of the object was not used and need to be used.

Now the scale is included and an average value is used because the axis change is not directly related to the stroke thickness.

fix for distortion, should avoid snapping back of geometry

Don't use undo for manipulator tweak operator

This causes problems when tweaking an operator

Fix divide by zero dragging the arrow

Cleanup: remove redundant access function
