Kernel: Implement somewhat functioning multithread support
...
This still uses only a single cpu, but we can now have 'parallelization'
This seems to work fine in qemu and bochs, but my own computer did not
like this when I last tried.
I have absolutely no idea how multithreading should actually be
implmemented and I just thought and implemented the most simple one I
could think of. This might not be in any way correct :D

It didn't make sense that dprint was defined in Serial.h.

planning on supporting any non x86 based architectures.

Kernel: Rewrite the whole VESA driver

We dont support vga text mode currently. I might add it later if needed.
I also removed mouse 'support' from Shell since it didn't do anything
and I didn't implement arbitary bitmap rendering to framebuffer
