Convert everything to new inline scheme (#57) (#72)

Browse Source 
* Convert everything to new inline scheme

* Add both extern and inline for some SSE vs. non-SSE functions

Some functions had nice, compact SSE implementations but bulky non-SSE
implementations, so this commit inlines just the implementations that make
sense. Also updated documentation.

* Convert HINLINE and HEXTERN to HMM_INLINE and HMM_EXTERN

# Understanding the structure of Handmade Math
Most of the functions in Handmade Math are very short, and are the kind of functions you want to have inlined. Because of this, most functions in Handmade Math are defined with `HINLINE`, which is defined as `static inline`.
The exceptions are functions like `HMM_Rotate`, which are long enough that it doesn't make sense to inline them. These functions are defined with an `HEXTERN` prototype, and implemented in the `#ifdef HANDMADE_MATH_IMPLEMENTATION` block.

* Put macros and return types on a separate line from the function definition:

HINLINE float
HMM_MyFunction()

// ...
}
```
* Explicitly initialize variables to zero:
```cpp
HINLINE float
HMM_MyFunction()
{
float MyFloat = 0.0f;
hmm_vec3 MyVector = {0};
}
```
* Put parentheses around the returned value:

Version | Changes |
----------------|----------------|
**1.5.0** | Changed internal structure for better performance and inlining. As a result, `HANDMADE_MATH_NO_INLINE` has been removed and no longer has any effect.
**1.4.0** | Fixed bug when using C mode. SSE'd all vec4 operations. Removed zeroing for better performance.
**1.3.0** | Removed need to `#define HANDMADE_MATH_CPP_MODE`. C++ definitions are now included automatically in C++ environments.
**1.2.0** | Added equality functions for `HMM_Vec2`, `HMM_Vec3`, and `HMM_Vec4`, and SSE'd `HMM_MultiplyMat4` and `HMM_Transpose`.
