Mathias Stearn 061a086641 SERVER-10165 aggregate() shell helper now returns a cursor
The actual change is in src/mongo/shell/collection.js with the remaining changes
to adjust tests to the new api.

The "ideal" arguments are now an array of pipeline ops and an optional object
with extra top-level options for the command (such as {explain: true}. For
backwards compatibility, we still support the varargs style where each argument
is a pipeline stage, but there is no way to specify extra parameters in this
mode.
