Bootstrap changes

[Timmy Douglas]

I added a "rebootstrap.slate" slate file to the end of the bootstrap
process to use the new compiler to build all the slate libraries over
again that were precompiled by the bootstrap. This has the benefit of
storing more information in the compiled method object to aid in
debugging. The debugger takes advantage of this by putting the source
locations next to frames in the backtrace:


Slate 2> [1 + b] do.
We are entering the debugger...
