[SM-DEVEL] "Final" patches for speed improvements SM

[Marc G. K. <ma...@it...>]

Hello,

For the people who are interested in speed improvements in SM I attached
the files involved.
See other postings for explanations.

If it works without problems on other servers then cyrus please post it so
the code can be considered as stable.
Other changes i made are:
cut == 'true' where booleans are involved. (thread_stuff).
I changed most of the lines where there was a check like this:
if ($var == 'true) or if ($var = true) and changed it to if ($var).
same for if ($var != true => if (!$var)


Marc.
