Add a kernel crash function, add a timer using the timer interrupt and

set PIT interval to 1000hz, use a vector inside Framebuffer, remove
without_interrupts from the framebuffer and serial console, move to
usize on primitives, add date at boot and turn on multithreading, add a
boot animation and add a test_performance function with the new timer
