Integration of ToLua with Ellan Jiang's GameFramework

GameFramework

URL: GameFramework
Commit: dc1ea7ccced00c834437a3f347b5dd72549bf36f
Modifications:
- Add necessary game objects and components in GameFramework.unity.
  - Tick procedures on Procedure Component but still select Procedure Launch with which to run the project.
  - Select Package mode on Resource Component so it won't check for resource update/download.
- Git ignore AssetBundleBuilder.xml since its output directory field depends on your own folder structure.

Core functionality: Assets/GameFrameworkExtensions/Lua/Scripts
- LuaComponent extends GameFrameworkComponent and provides features of loading and running Lua scripts.
- CustomLuaLoader hacks ToLua's file reading mechanism so that asset bundles built by Game Framework will work.
Usage example:
- Assets/Scripts/ProcedureXXX.cs
- Assets/LuaScripts/XXX.lua
Editor helper scripts: Assets/Scripts/Editor

Download this repo and open it in Unity (5.3 or newer).
Create your own AssetBundleBuilder.xml file according to Game Framework examples, especially the output directory for asset bundles.
When assets are imported and source files are compiled, there will be a Game menu showing in the Unity editor. Select it and click Build AssetBundles to build lua scripts into asset bundles.
Copy all Package assetbundles of the platform on which you're going to run the project into Assets/StreamingAssets/.
Run the game in the editor or build and run the game on any platform.

If you tick Editor resource mode on the Base Component of Game Framework, CustomLuaLoader reads the Lua files on the disk. Otherwise, the project, when launched, first loads the asset bundles that contain Lua scripts so that CustomLuaLoader gets the script contents later from the loaded (and hence cached) texts.
Currently .lua files will be recoginized by Unity as default assets, rather than text assets, so that you cannot load them directly from some asset bundle. So AssetBundleBuilder.cs add .bytes extension to the file names before building asset bundles and revert them afterwards.
