right now, it only works for int prefs. fix#15230, heed and reflect the quoted style and quoted size prefs
in the html select widget in pref-mailnews.xul.
rewrite the html select elements in the pref xul, to work correctly.
remove unused, commented out xul to avoid confusion.
add new option for "yesterday" for the news offline download pref.
use nsCOMPtr. use PR_snprintf() to avoid potential buffer overruns.
use #defines to clean up the code. use PR_sscanf instead of sscanf.
