Add support for Lua 5.2 and cjson.new

Update all Lua scripts to use new module init style everywhere:
	local json = require "cjson"

Lua CJSON does not register a global table under Lua 5.2. The global
table can be disabled under Lua 5.1 with DISABLE_CJSON_GLOBAL.

Other changes:
- Store CJSON configuration as an upvalue for each function.
- Add "cjson.new" function to create another module table with a
  separate configuration.
- Add _NAME and _VERSION variables.
