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.

Kernel: Add a heap memory allocator
...
This is the first time I've actually dropped liballoc in favor of writing my own implementation.
Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job.
But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code!
