Start app command enhancement

Is your feature request related to a problem? Please describe.
There are some options which can be controlled from start of the game like language which port the game is going to run on and etc.
Also there can be some situations that GOD wants to choose which role to be played or not in the game.

Describe the solution you'd like
Probably using argv to tokenize these options can be a solution.
