Fix use of abs() function with float argument.

The abs() function in stdlib.h takes an integer argument. Passing it a float
will silently convert the argument to int, and take the absolute value of the
result. Hence, abs(0.99) == 0, which is not what was intended. Use fabs instead.

The cross product is only defined for 3D vectors. Instead of checking the size
at runtime, only provide an implementation for N==3. Trying to use the cross
function with other vector sizes will then result in a link error.

Excessive parentheses only make the expressions hareder to read.

Replace use of float by double.

All values in a quaternion are declared double, let's not lose precision on
platforms where double is larger than float.

Simplify several functions by replacing the body with one-line calls to the
constructor. Furthermore, pass Quaternion arguments by reference to avoid
excessive copying.

Quaternion needs the definition of a matrix. Include it.
