#16 Add ability to send press from press-reading screen
Add the press recipients checkboxes and press-text typing area to the screen showing received and sent press, to allow the player to refer to text in a piece of earlier press while typing new press. Do not pre-fill the text to be sent, but consider pre-filling the checkboxes presuming that the intention for any press written while reading a specific press message would be a reply to the sending power (or to all receiving powers). Warn if leaving the page after typing some text but not sending it. If the pulldown is changed to show a different press message, and if text has been typed for an unsent new press, leave that (and the checkboxes) unchanged. Note that this may require client side JS code for pulldown-change handling, and creation and use of an AJAX service.
