Bitbucket Snippets macro is completely broken

[David Simpson]

The demos here aren't working at present:

• https://dvdsmpsn.atlassian.net/wiki/display/bitbucket/Bitbucket+Snippets+Macro
• https://dvdsmpsn.atlassian.net/wiki/display/bitbucket/Examples+of+all+macros

It looks like something must have changed in the API.
