Thonny-ev3dev

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

Removed
- don't build sdist and upload packages anymore, because these wheels are also source packages
and are better because they contain the requirements in metadata of the package,
which thonny can fetch from the pypi server before installing.

Added
- added building of wheels and uploading them to the pypi server

Fixed
- adding the thonny-ev3dev package as a wheel fixed the refusal of thonny
not installing the plugin with the message "Thonny plugin without requirements".
The wheel fix it, because the install_requires from setup.py
is stored in the wheel's xxx.dist-info/METADATA file under the Requires-Dist keys.
The pip installer can then fetch this information from the pypi server under the
info.requires_dist field, and then Thonny gets its wanted requirements.
