IDEA-130889 push dialog cosmetics: community repository is truncated

* TreeUI  with NodeDimensionsHandler overrides to avoid problems with initially wrong node sizes;
* component listeners added to track current scroll bar size and update node sizes according to it;
* setRowHeight moved  to the end of push log constructor, because it calls resize and repaint components;
* set minimum tree size and use it as minimum node size when scroll bar is not initialized yet;
* note: add DebugMarkerBorder in RepositoryNode renderer if needed
