Upgrade to Meteor 0.6.5.1 (namespacing, build system).

* `Meteor.http` renamed to `HTTP`

* CoffeeScript globals exported via `share` variable.
There seems to be some bug with 'strict mode' and the share variable; we
throw an exception if the __coffeescriptShare variable isn't defined before
lib/model.coffee executes.  Create a new lib/000workaround.js, which ought
to execute first, to workaround this by preemptively declaring
__coffeescriptShare.
