Update README.md

in setup.py use version from ev3dev2simulator/version.py

added version [1.0.4] - 2020-02-28

 ### Added
 - improved Options menu by adding label  "Warning: to use the simulated bluetooth in the simulator make sure you have PyBluez uninstalled!!"
 - improved Options menu for windows we only have option "show simulator
   fullscreen on second screen" because on windows for none fullscreen mode the
   simulator is always opened on the default screen.
 - improved Options menu for macos where we  only have two options "show simulator
   fullscreen" and "show simulator on second screen". Latter option is added because
   when dragging window to other screen sometimes messes up the resolution of
   the window. By drawing the window already at startup at the second screen
   prevents this problem.
 - improved Options menu by adding caption which explains the rpyc timeout you can configure under advanced options.

 ### Fixed
 - fixed cleanup of files on EV3 by switching to new ev3devcmd library

use console_scripts for simulator in setup.py because although it is …

…a gui program we want to start it from the console with some help options!
