Heap: Add a new block to the end of the linked list
...
*facepalm*
This was causing page faults when having two blocks and the first one (oldest one) being freed first.

Here's one advantage of Rust over C++:
Immutability by default. In Rust, you have to mark a variable as mutable, whereas in C++ you have to mark it as immutable.
What's the problem here? Usually, most variables don't need mutability. Thus we end up with const all over the place.

Please use make<T> and destroy<T> instead of new and delete
...
Those are there only for common stuff (in the Luna library) that needs an environment-agnostic way of allocating memory.
new and delete are standard, thus we should use those.
