Adds support for Lua struct library so one can pack/unpack binary structures
This is based on Roberto Ierusalimschy's struct library, along with additional
options based on Flemming Madsen's patch to the lua-users mailing list, and
some changes I made to support 64-bit integer packing/unpacking. Details
are in the top comments for wslua_struct.c. This also includes a test script.
