Usual UI messages fixes...

Sculpting: Move lock options in symmetry panel.

Lock is an often used option according to artist feedback, so better
have it on the same tab as brush tools.

Add header info for the Walk Navigation operator

Motion Tracking: Grammar fixes.

UI / 3D View Tool Shelf: Avoid redundant "Grease Pencil" label, now that GP has its own tab.

Fix T38610: lattice U/V/W should not be animatable, is not supported.

Code cleanup: ndof view3d operators use of ViewOpsData

View3d: fix for ndof with quadview+box, missing sync.

also de-duplicate 3x pan-functions.

NDOF: print events when debugging is enabled

NDOF/X11: skip getting the time when no ndof events are processed

NDOF/X11: fix for glitch using ndof outside the view and entering again

NDOF: minor color picker improvements

- swap Z/Y axis so Z changes hue and X/Y change location.
this way you can use ndof like a joystick and Z rotation like a dial
for the hue.

- change sensitivity when shift is held to be 1/5th

NDOF: fix for negative colors and flickering hue when picking with HSVCUBE

View3d Walk: enable rotation for ndof by default

Code cleanup: replace WM_OT_ndof_sensitivity_change -> WM_OT_context_scale_float

also increase maximum sensitivity

Freestyle: Fix for chaining operators not concatenating edges with Freestyle edge marks and at material boundaries.
Problem report by Postoman on the BlenderArtists.org Freestyle thread, thanks a lot!

Fix/workarond for scenes rendered for sequencer preview

This is really a workaround which brings back direct display
list creation from drawing code. This is rather nasty to do
but proper solution would require some major sequencer redesign.

View3d: enabling quadview box would copy view offset, sync to avoid jump

View3d: fix for quadview box only syncing some view axis

View3d: add utility function to get the quat from a view axis
