Center text without needing endless spaces; also support \n in centered text.

* Text positioning in message boxes is now controlled by #defines.
* The various MSG_PLAY_SLIDE<n> messages are now one, MSG_SCREENSHOT_SLIDESHOW_KEYS, with \n between lines.
* Use \n in some more message pairs.
* Lengthy scrollers broke. This will be investigated in a later commit.
