Ikarus Scheme 0.0.2

This milestone for ikarus will achieve the following:

1. Speedup of compile time
    * bootstrap time was cut from around 11 seconds down to less than 7 on my macbook
    * the compiler benchmark (11000 lines) now compiles in about 3 seconds down from 10.
    * the slatex benchmark (2350 lines) now compiles in under 1/3 of a second.

2. Speed up of run time
    * Any code that's floating-point intensive gets a huge boost in performance.
      (fibfp runs at -43%, fpsum at -46%, mbrot at -28%, pnpoly at -29%, sumfp at -48%, ray at -28%)
    * Closure sizes have been optimized. Closures no longer close over the library's top-level variables.

3. 90% of R6RS (up from 80% in the 0.0.1 release)

4. Numerous bug fixes (thanks to all who submitted bug reports and suggestions for improvements)
