New build - Free Look Z-roll implementation

[llafnwod]

Hey folks,

Dolphin has a Free Look option under the Graphics settings that allows camera y-axis and x-axis rotation (camera pan and tilt), but the main branch doesn't have z-axis rotation.

I've implemented one. It's currently bound to SHIFT+C/X (clockwise/counterclockwise). It's useful in third-person OTS games, like Zelda, since just panning and tilting can throw off the camera orientation. You can set the speed with SHIFT+(1/2), like the WASD movement.

Here's the build (based on master-5991), if you want to try it out:

Two questions:
a) Does anyone care? and
b) If so, can we get this included in the main branch?

Here are the source changes:
(Linear Algebra)
MathUtil.(h/cpp)
VertexShaderManager.(h/cpp)

(Hotkeys)
ConfigManager.cpp
CoreParameter.h
Globals.h
HotkeyDlg.cpp
HotkeyManager.cpp
VideoConfigDiag.cpp

(Implementation)
Frame.cpp

Thanks, and let me know what you think!

Where is the source?

Lol, my bad. Find attached.

If you want to get this into the main branch, I suggest making a pull request. It's the standard way to make changes for both new contributors and veterans, and the developers look there much more often than here. I haven't looked at the code you changed, but the general idea of the change sounds good.

Thanks! Cloning Dolphin is literally the first time I've used GitHub; I'll do that.
