Launcher improvements

Today I worked on a minor update for my game Slendertubbies and added a new settings feature for the launcher. Currently there is only one setting which allows players to disable the launcher when starting the game. This is a major change because it allows players to have a more personalized experience with the game.

I also updated the documentation, fixing some language errors among other things. 

I also removed some unnecessary files  that were  unrelated  with game.
