This was composed by taking the SETUP text messages from Localisation\Text.csv and combining it with the order of Message Settings as found in Interface\Messagetypes.txt, by a join on the game's internal name for each Message Setting (e.g., #1 is NEWMONOTHER). A bud helped me QA every line of the collation against what's seen in the game; everything was perfect. It's for v. 1.3.
The seven Settings near the end that have asterisks had internal names in Messagetypes.txt, but no SETUP entry in Text.csv. I copied them by hand, and then in a search across files I found the text of #212 in Localisation\text112.csv. So presumably all seven were added later (by patches or whatever).
