5481aa7097 Fix a bug in single->half conversion. 
The original C code had if(m & 0x00800000) which is true if the
expresssion does not evaluate to zero. This was inncorretly translated
to the C# code if((m & 0x00800000) == 1) which only evaluates true if
the expression evalaute to 1, which it never does. The correct test is
to test not equal to zero (!= 0).

6856fe5e71 Merged remote-tracking branch 'l3m/matrix4d-quat-fix' into develop 
Updated the Matrix4d CreateFromQuaternion methods to actually create
Matrix4d. They now mirror the Matrix4 CreateFromQuaternion methods,
just using doubles and the -d classes.

Previously, Matrix4d.CreateFromQuaterion actually created a Matrix4
from a single-precision Quaterion.

fc1a8e022b Fix for setting Matrix/Vector values by Index 
Many Matrix*/Vector* implementations were throwing
IndexOutOfBoundsException when you tried to set their values via their
indexer due to a missing else statement.

b38c81a458 Added Matrix clearing methods 
- Added ClearTranslation(), ClearScale(), ClearRotation() and
ClearProjection()
- Added ExtractProjection() to Matrix4

ca7e2c9c4b Copied Matrix4 changes to other classes 
* Removed  pointless LengthSquared check from ExtractRotation()
* Improved inline documentation

498b659d58 Changes suggested by Rob Rouhani 
* Turned the new Matrix4 properties into methods
* Matrix4.Normalize() now behaves correctly. ExtractRotation() does its
own row normalisation.
