Optmize Show Public Poll Results

Time for another vb3 optimization, don't you think.

This hack reduces the ammount of queries generated by the show poll result feature, when it's a public poll.
On larger boards with a lot of votes, this can have a very strong effect. find out more here: https://vborg.vbsupport.ru/showthread.php?t=66689

Cool I'm always up for an optimization.

How does this optimization relate to This Bug Report & Fix?

[Dean C]

Thankyou for sharing your work Stefan

[Xenon]

@The Sandman: well, this hack is the solution for the bug report

the nested query isn't fixed in the bugtracker, just the index structure is changed, but that doesn't reduce the ammount of queries.

I have a small board but I installed this anyways
