Update _host_game_aiter to accept rgb_render_config and random_seed args

[islamelnabarawy]

A minor change adding the rgb_render_config and random_seed args to _host_game_aiter and passing them along in its implementation.

This also adds an unprotected (without the underscore) version of _host_game_iter called run_game_iter

This branch is based off master but can be rebased to develop with no conflicts (see: run-game-iter-develop).
