Please update the instructions

Hey,

First of all - thanks for nice plugin!
Second - please update the instructions how to use it:

• In your demo project, you are using three android permissions, which are enabled in Export -> Android -> Permissions: Access Network State, Get Accounts and Internet. It should be mentioned in the instructions
  
• As it was figured out by @hlfstr here: Sign-in callbacks don't work #5 (comment)
  the callback for _on_player_is_already_connected() requires 2 parameters. So the following will work:

func _on_player_is_already_connected(status : bool, id : String) -> void:
	print("hello from _on_player_is_already_connected\nStatus: %s | ID: %s" % [status,id])

• First argument in function
  play_games_services.show_saved_games("SNAPSHOT_NAME", allow_add_button, allow_delete_button, max_saved_games_snapshots)
  is not the SNAPSHOT_NAME, but is the title of UI screen with saved games, so for example it could be "See My Saves"
• To avoid errors with authentication, you should advise users to firstly go through all of this page: https://developers.google.com/games/services/console/enabling

Hi @ja-kub , thanks for the feedback. I have updated the plugin to use the new Android plugin system for Godot 3.2.2+, also I've updated Readme.md file. Please check it out, and tell me if you find it easy to follow. I followed the new instructions from readme file and found out it pretty straightforward. Thank you!

I see that none of these 4 updates were done.

There is a quick description regarding your points:

1. You don't need those permissions. All those permissions were added accidentally.
2. I removed this method. It is not used in the new plugin. If you need it I can add it back but create it synchronous .
3. I am going to update it now.
4. Actually it is present in the actual Readme.md. Please check again. Right after Getting started.
