Main::PSGI: use to_json(..., {ascii => 1}) instead of encode_json(...) in _json_response. That's more portable format.
xt/Input_Twitter.net.t: test with Net::Twitter::Lite::WithAPIv1_1
Change the error handling specs of callback-style methods (Main, Timeline, StatusStorage). It's best to have $error at the first argument. Fix tests regarding StatusStorage. Still need to work on tests for Timeline and Main.
Also, watch_spec argument for $timeline->watch_unacked_counts() is now a hash-ref instead of a hash. This is consistent with $main->watch_unacked_counts() method.
Timeline: change API of watch_unacked_counts(). Now it takes named arguments, which is more consistent with other methods of Timeline. t/Timeline.t is fixed.
Main POD: watch_unacked_counts now takes named arguments. t/Main.t is updated. Not yet implemented, though.
StatusStorage::Memory: fix implementation for updated API. Pass the tests.
Timeline: fix implementation for updated API. Pass the tests.
Main: fix implementation for updated API. Pass the tests.
Main::PSGI: fix implementation for updated API. Pass the tests.
