Features

- Improve performance of runtime by more efficiently unboxing known fixnums.

- Added `char-ready?` to `(scheme base)`

Bug Fixes

- Avoid generating C code containing unused variables. In addition to generating better code this also prevents the C compiler from raising associated warnings.
