Math: added vector3.rotate() and matrix3.rotation() methods
these operate on a "enum Rotation" which defines a set of standard
rotations. These are much faster than our previous method, plus use
less memory

Vector3<T>() { x = y = x = 0; }
changed to :
Vector3<T>() { x = y = z = 0; }

Back out the memset optimisation. It helps with code size but causes inexplicable link-time failures (undefined references to __cxa_pure_virtual).
Thank you very much Mr GCC. Can I have my evening back?

Minor code size optimisation; use memset to zero *this rather than explicitly assigning zero to the vector elements. Still not quite optimal for matrix3 as it gets three memsets, but still cheaper in terms of code size.

AP_Math - initialise vector2 and vector3 x,y,z values to zero. Doug found (and I confirmed) that if vectors or matrices were declared in a function (i.e. a local variable), they would often have non-zero values. Global declarations don't have this problem - it's a C++ performance thing it seems.

Rather than subclassing from the templated classes, just typedef directly to them.
This should solve the issues related to assigning to the convenience types.

Remove a bunch of probably wrong const cruft. Ditch the dubious array index operators from vector2.

Remove the trivial operator= implementations, the default shallow copy is fine.

Some minor fixes prompted while looking at the code for other reasons.
Return non-const values from assignment. Fix operator* for matrix3.
