Keymap: remove some hard coded transform events

Also re-order for display purposes

Merge branch 'master' into blender2.8

Cleanup: right shift

3D View: select exclude w/ ob-center enabled

Annotation Eraser: Only operate on the active layer

Since we aren't exposing per-layer locks here (as we want to avoid
having lots of work enabling/disabling locks), the eraser now only
erases strokes on the active layer

Cleanup: Assorted little tweaks/moving code around

Annotation Eraser Tweaks

* Remove the "soft" modes from the annotation eraser. Now, erasing
strokes will immediately remove the stroke points. This works better
for annotation use cases, as when erasing strokes, you usually just
want to get rid of the notes quickly.

* Show eraser brush size setting in the topbar/tool settings when the
eraser tool is active. (Note: This setting still uses the userpref
setting, which we should move to the scene toolsettings instead
so that it doesn't get reset with each session)

Cleanup: Deduplicate stroke freeing code

Merge branch 'blender2.8' into greasepencil-object

Fix: reorder variable initialization and usage

Fix: X Randomization -> Random X

Fix: rename PrincipledHairBsdfNode's melanin stuff

Fix: lower_case OSL variables

Fix: remove random value from closure

Fix: hide Random value if unused

Cleanup

Fix: OSL shader used both the wrong and the unadjusted type of roughness

Merge branch 'master' into soc-2018-hair-shader

Week 9 merge: no issues

Lift upper bounds of roughness/radial roughness
