Ikarus Scheme 0.0.3

The 0.0.3 release of Ikarus brings the following improvements:

1. System usability.
When Ikarus encounters a syntactic error (either during reading or during macro expansion), error messages now contain the file name and character position at which the error occurred. Previously, you got a context-free error.

2. Better Unicode support:
Ikarus's ports are now properly classified into either binary or textual ports (previously, they supported mixed character and byte input/output). The UTF-8 and Latin1 codecs are now fully supported for both input and output.

3. Closer R6RS conformance:
The 0.0.3 release adds 28 new R6RS primitives, bringing us to 94% of the total R6RS forms and procedures.

Additionally, many existing primitives have been improved (either on the performance front or on generating better error messages), along with some improvements to the compiler itself.
