LuaJSON 1.3.1 Released

LuaJSON 1.3.1 released! If you use luarocks, just use luarocks install luajson since it should soon be in the repository.

This release's changes include:

• Documented and tested compatibility with Lua 5.1, 5.2, and LuaJIT-2.0-beta10.
• Documented and tested compatibility with the 'classic' strict module on Lua 5.1 and LuaJIT-2.0-beta10 as provided by the LuaJIT-2.0-beta10 package.
• Tested after-the-fact compatibility with Penlight's 'pl.strict' module for all supported Lua versions.
• Fixes supplied by François Perrad included to address problems found in 'strict' library handling.
• Users of the direct 'json' module will have a polluted global environment with the 'json' module populated unconditionally.

If there are any other Lua environments that you would like added to my test matrix, please let me know. I am always open to suggestions and improvements. I host the project on github at https://github.com/harningt/luajson, so feel free to fork and submit merge-requests :)

A note on the 'json' module pollution: if there is a general consensus among users of the library (wherever they may be), I'll happily remove this pollution. I much prefer Lua 5.2's way of handling modules and don't mind the fact that creating a Lua module without the 'module' function has the side effect that Lua 5.1 doesn't even have the global pollution.
