Ide 1.5.x enhancements: serial autostart and autosave editor window size

**PLEASE CLOSE THIS REQUEST. THIS WAS ONLY FOR ONE COMMIT AND IS SHOWING MANY OTHERS.**




I've created two small enhancements targeting 1.5.x:

* Add preference serial.autostart to start serial monitor after a successful upload (Martin Falatic) By default this pref is false (setting it to true in local preferences will enable it)

* Save editor.window.{width|height}.default values based on last editor window closed (Martin Falatic)
