This is the start of the implementing for the Linux platform. I aim to make this as similar to the Windows platform as possible, although due to the fundamental difference in the two OS's, there will be things that need to be different. As such, I will be using the Windows platform files as a base, and reimplementing the functions with Linux equivalents. I am sure this will have bugs, which by my best attempt will be fixed when found.
