Handle interrupts

Currently handles exception 8 and IRQ 1. EXC8 is double fault, and IRQ1 is
keyboard. EXC8 handler puts out a ':(' on the top left corner of the screen and
halts the machine, while IRQ1 puts out a string on the screen. However, it will
only do so once, and I have yet to figure out why.
