Fabric-taskset

------------------

- private ``_expose_to`` method now returns list, not generator.

----------------

- ``task`` decorator is deprecated and replaced with ``task_method``.
This was a bad name because of ``fabric.task`` decorator
(thanks Denis Untevskiy);
- ``Taskset.expose_as_module`` method that allows to use TaskSet instances
from command line without creating dummy modules on disk
(thanks Denis Untevskiy).

----------------

Initial release.
