Scripting: Implemented System.RuntimeInfo

Implemented a read-only System.RuntimeInfo String property that returns the information formerly displayed when pressing Ctrl+V in a game. Placed the old Ctrl+V shortcut behind a game file version check to ensure that Ctrl+V isn't intercepted by default for newer games. The debug implementation of `debug(1, 0)` still works in debug mode. Internally, it just calls System_GetRuntimeInfo and displays the info. The System.RuntimeInfo property exists in debug or release mode. The user may implement the display of this info however s/he likes.
