The QUOTES.TXT file must exist (when using an external editor configured in
SCFG as "All" or "Prompt User"), but we don't expose `sbbs_t::quotemsg()` in a
JS method and don't call it automatically in `bbs.post_msg()`. This leads to
custom message readers needing to do their own QUOTES.TXT file generation,
e.g.:
https://gitlab.synchro.net/main/sbbs/-/blame/master/xtrn/ecreader/lib.js#L692

Or else risk getting errors like this when trying to post replies via JS:
```
 !ERROR 2 (No such file or directory) in writemsg.cpp line 396
(writemsg) opening "/sbbs/node1/QUOTES.TXT" access=0
```

This issue likely impacts other message creation functions too (not just
`post_msg()`).
