Tycho 0.2 Released

[timmac...@gmail.com]

Various release notes:

* Objects are now even more lightweight using the `object {...}`
syntax
* Actors have first class syntax with `actor _function_`
* `compile` and `eval` by Matthew Wilson (diakopter).
* `method`, `dispatch` (same as switch in C#), `with` (same as using
in C#), `dispatch-method ()`
* Macros can be placed in order of other syntax using `macro _name_ >
_other-syntax_ ...`
* Lots of bug fixes
* Module system works with file system, `home:` takes modules from
base directory of tycho installation, `world:` takes modules from
http://tycho.googlecode.com/svn/trunk/Modules, and all other
namespaces map to files in the current directory.
