Add space for facegroup storage

Widgets:

* Move lamp operators to a proper place
* Store a list of widgets to avoid polling too many times
* Fix wrong indices when widgetgroup was not used.
* Lamp widget now uses an arrow widget. This will be refined to make a
nice prototype for operator/widget interaction.

Use a property to make the transform operator widget driven.

Design is still pending here, but for now just use to not remove widget
display.

Change dial to something that resembles current rotation widget better.

Dial widget, used in rotation manipulator code.

The widget can still change in the future, also widget styles can always
be used to create new widget visualizations.

Implement non-3D drawing per widget.

Basically, 3D widgets stay the same size whatever the zoom is in 3D
view. Ported over from manipulator code.

Switched back to blender implicit solver for merge.

Unified the main Eigen solver function a bit for constrained/unconstrained
solver variants.

Ported the remaining implicit solver functions for Eigen.

Also added a couple of utility wrapper functions for Eigen types to make
interfacing with plain float arrays and blenlib math easier.

Updating Eigen implicit dynamics solver implementation to adhere to the
new mass-spring solver API.

Compatibility fix for shape keys.

Avoid moving the 'from' pointer around in DNA. This way files stay back-
as well as forward-compatible. Only the additional type enum and
sub-index is stored in a new from_extra struct in shape keys now.

Fix for invalid ID access during versioning.

For now is fixed by doing a versioning hack in the lib_link function,
but would be nicer to avoid this altogether for forward compatibility.

Interpolation for non-simulated hairs in preview.

This generates a somewhat believable overall look for the hair system
by blending simulated hairs. For small number of hairs and small
preview ratios this can get quite inaccurate, but that's the tradeoff
for getting preview functionality ...
