Add changelog for 0.6

This is also the first non-GSOC commit, so this is not synced back to
gsoc.svn.wordpress.org. Goodbye to `git svn dcommit`, it's been fun!
Bump JS version to 0.6
Only access superglobals in a single place

This ensures that the only superglobal usage is *before* dispatching, allowing
dispatching to be used for internal routing.
Pass server object into API objects

This avoids using the global $wp_json_server, which helps with internal routing
and usage of the API functions.

Merge pull request #10 from kokarn/master

Return all term data, not just the last term
Add term_link in term data
Preparing meta using get_post_meta

Maybe it's better to use get_post_meta instead has_meta, as this way we make use of the caching system. And i don't think the meta id is relevant in any way
Add term_link to prepare_term

Maybe it's a good idea to add the term_link to term data, as we can't get it in any other way. Or there is another way?
Update class-wp-json-taxonomies.php
Remove term_link from master, added in patch-2
