v0.83.0 : Introduce big changes for the future ;-)

The "runners part" will completly be redone, in future release (>0.90).
Here it's just a test version ... for test purposes.

spoil : all runners (for desktop/android) would be removed : there will be only one, which would provide all features in pure python (no dependancies!) ... there will be only 3 ("pyscript", "pywebview" and the new one (which will work for android, desktop and/or chrome app mode)) : it will be a lot simpler ... to maintain, to explain and to use.

Don't use the new runner .... its name will change soon.

All current runners will be deprecated from 0.90.0, and removed in 1.0.0 !
