Added checks to be sure paging is actually enabled on the cpu.

- Made a special assembly file to put CPU check function in. E.G. functions to get the state of
	specific registers

In this case I have created a simple assembly function to get the contents of the CR0 register.
With the help of the c++ preprocessor the value can then be used to check if certains bits are set.
For example to check if the PG (paging) bit is set, indicating that paging is enabled for the
processor.
