Fixed some bugs in ARP and TCP Code

- also I need to learn not to use "git commit -a" when using git add.
- Last commit also had some huge changes to the Video architecture
 > Made the video mode only describe the resolution and colour depth.
 > Text/Framebuffer/3D are now controled via an IOCtl that swaps buffer modes
 > An IOCtl (still to be put in) will provide feature flags for the VTerm to read
