0.2.0

Added

• Array.join method, similar to PoolStringArray.join
• Project Settings for setting up package.path and package.cpath
• Bundle LuaJIT's jit/*.lua modules in build folder

Fixed

• Error handler now uses tostring to stringify the incoming parameter,
  avoiding type errors. It also checks for the result of string.match, so it
  does not errors if the message is not in the format expected.
• Loading of C modules now uses absolute library paths, so that files found in
  patterns like res://* are correctly loaded.
• Always try loading active library, so that dynamic loader knows about lua*
  symbols when loading C modules.
• Pool*Arrays' __gc metamethod
