This commit provides `zip_{first,shortest}` with the standard member types and
methods expected of iterators (e.g., `difference_type`), in order for zip to be
used with other adaptors, such as `make_filter_range`.
Support for reverse iteration has also been added.

This augments the STLExtras toolset with a zip iterator and range
adapter. Zip comes in two varieties: `zip`, which will zip to the
shortest of the input ranges, and `zip_first`, which limits its
`begin() == end()` checks to just the first range.
Recommit r284035 after MSVC2013 support has been dropped.
