Vaadin (14+) Flow integration of ace-widget. As last author is not active from two months, I've decided to create component on my own and try to fix some of the bugs. It's my first component so I know that not everything will be perfect. I'm counting on suggestions. What's fixed: + Added HasSize and HasStyle. + Added ValueChangeListener. + Fixed missing ace-builds import. + Fixed NullPointerException when setting sizes. + Fixed editor div height. + Fixed getValue() method.
