boot system and buildkernel - Remove the thrice damned forth interpreter

boot system and buildkernel - Remove the thrice damned forth interpreter

* Remove the forth interpreter from the build.  The last straw was when
  I tried to fix the module path and 6 hours later still couldn't get
  it right.

* Write a C based menu system and loader, replacing what the forth code
  used to do.  This is about 85% complete (tftp and boot chaining issues
  are not handled).  This took exactly one day to do, by the way.

* Reformulate installkernel to now create a directory /boot/kernel.blah
  and place the kernel and modules inside that directory.
