KeraLua LuaDebug properties all return the same data

[mandrewpowers]

Every property is returning pname instead of using their respective string pointers. I noticed when trying to get the source of a function call in my project.

src/KeraLua/LuaDebug.cs:

		public string name
		{
			get
			{
				return new CharPtr (pname).ToString ();
			}
		}

		public string namewhat
		{
			get
			{
				return new CharPtr (pname).ToString ();
			}
		}

		public string source
		{
			get
			{
				return new CharPtr (pname).ToString ();
			}
		}

		public string shortsrc
		{
			get
			{
				return new CharPtr (pname).ToString ();
			}
}

I created a pull request that should fix it.
Edit: Seems to fix it (http://i.imgur.com/3uKi7Pv.png).
