[ANN] SIXX 0.2c is available on all major Smalltalk dialects

Hi all,

I've updated SIXX to 0.2c. A new hook #sixxReferenceIdInContext: is useful
for comparing SIXX files by usual diff tools.

<<New Features in 0.2c>>
- Fraction serialization/deserialization support.
- SixxReadStream can read no-root-tag sixx format.
- Added a new option "SixxSettings>>useReducedTags"
    If this option is on, RIXX (Reduced SIXX) will be generated.
- Bug fix of ShapeChanger
- Added a hook "Object>>sixxReferenceIdInContext:"
    By overriding this method, you can use your domain object's id in SIXX.
