Buildsystem: Removed include/basalt_window.h. See prior commit #cac50b01

Library:
Added logging and memory modules.
The logging module provides a flexible interface for adding and removing logging streams (think stdout, stderr, a file) and supports ANSI colouring and including the date and time of each log call. Its header also provides several definitions for assertions, each corresponding to a specific log level and some other side effects such as debug_break(), returning, exiting or doing nothing.
The memory module wraps (_)aligned_alloc and free functions and includes memory tagging by class and location and the ability to fetch a formatted string containing this information. This can allow you to narrow down where memory leaks and double frees occur to particular sections within a module. Memory can be aligned to any, 32, 64 or 4096 byte boundaries using this module.
