Fixed unnecessary copies of copyable result types when futures are used as rvalues. Propagating exceptions for move-only types are now scheduled on the executor (I'm not sure why they were not scheduled before). Added copy() algorithm to utility.hpp to explicitly copy objects. Added docs and tests.
