74114 - add hidden pref to disable thread as a sort

Status: VERIFIED DUPLICATE of bug 72493

(SeaMonkey :: MailNews: Message Display, defect)

Description

[(not reading, please use [e-mail] instead)]

right now, we treat threading as a sort, like 4.x does.  

NS6.0 (and earlier versions of mozilla) didn't treat it as a sort, and people
really liked that.  This meant they could go into threaded mode, and sort by
whatever.  Currently, threaded mode is always sorted by order received.

we could easily bring it back, and make it configurable by a pref.  (default
would be the 4.x way.)

two things need to be done:

1) I need to fix the .cpp and .js where I use the sort type (instead of the view
flags) to determine if I'm in sorted mode.
2) we need to settle on how we want the UI to work.

on suggestion:

if the hidden pref was enabled:
clicking on the thread column would thread, sorted by what ever column was last
sorted.  the indicator would remain on the old column.
if in threaded mode, clicking on another column would take you back out of
threaded mode.

this means if you want to go from threaded sorted by subject, to threaded sorted
by date, you have to click on date column and then on the threaded column.
