Working on Lua call interface

At last weekend I started to look at lua scripting part of my application but “suddenly” find that ember scripting support lacks of ability to get return values from lua calls. Then Erik kindly made an scripting call context interface—it’ll be possible to get return value with it. So, my plan for next days is to clean up and bring it to state where it could be used for my task.

And task itself is stays the same—make a draft for lua scripting in my application.
