Improves cmake's ability to find our libraries on Windows / MSVC 2013

BLI_kdopbvh: Replace realloc's with BLI_stack

BLI_stack: various small additions

- add BLI_stack_count
- add BLI_stack_pop_n to pop into an array
- add BLI_stack_push_r, which returns a pointer that can be filled in

Also remove sanity check in BLI_stack_pop, assert if the stack is empty.

Fix T40964: Massive shading failures with glass node mixing, whiteouts and blackouts

No preemptive removal of muted and reroute nodes from compositor node
trees for localization (previews and viewer evaluation).

This is handled entirely by the compositor already. Doing this during
localization is redundant and risks divergent behavior.

Fix T41067: Muted nodes still do data type conversions.

Proxy operations from muted nodes would still create conversion
operations where the datatypes don't match, which creates unexpected
behavior. Arguably datatype conversion could still happen even when the
main operation is muted, but this would be a design change and so is
disabled now.

Edgehash: Improve magic number for hashing

Gives consistently better results. Tested with wide variety of meshes.

Fix T41074: Several Mouse Look actuators not working well together when reset button are set in one or several of them

Fix provided by lordloki (Jorge Bernal)

BGE: TrackTo actuator: increasing up & track axis options

This is related to Task T34861 to increase up & track axis options for TrackTo actuator. I've just added it to differential to facilitate an easier review.

With the patch applied you can select X, Y and Z axis for the Up axis, and X, Y, Z, -X, -Y and -Z for the track axis.

Related to the implementation I have used the algorithm from Trackto constrain placed in constrain.c but adapted to be used with MOTO library.

The wiki docs are here (http://wiki.blender.org/index.php/User:Lordloki/Doc:2.6/Manual/Game_Engine/Logic/Actuators/Edit_Object#Trackto_Actuator).

Test file is here: {F97623}

I have also uploaded 2 screenshots showing the UI modifications to the TrackTo actuator:

Fix T41044 Cycles Bake: world space location affects object space normal pass

Follow up to previous commit.

* Expose is_tablet property to events to determine if event contains
tablet data.
* Expose tablet tilt for events as a 2D vector in python

Feature request:

Expose pressure from event system to python. This will return the tablet
pressure, if a tablet is present, or 1.0 if not.

GHash, EdgeHash: add debugging function to measure the hash quality

Can use to check on improvements to hash functions.

Error in last commit

Py/API: add bmesh.utils.face_split_edgenet

Tooltip improvements for modifier functions

Remove redundant NULL check

BMesh: avoid redundant normalize comparing angles

Math Lib: add compare_len_squared_v3v3 from paint branch

Math Lib: accept a limit of 0.0 when comparing vectors
