[client] published image button states

* always show "public images" button
* hide the "upload to master" button instead of disabling it if the sat doesnt support it
* introduced Session.isImagePublishSupported instead of multiple satApiVersion checks
* added SelectionListener for ImagePublishedWindow to en/disable download buttons on selection change
