//Enhanced showPoll block
// Shows poll in block from specified topic,
// or the most recent from specified board
//
// Author: Greybrow
// Version: 2007-04-24 22:00
// Features:
// shows poll (or polls) that fits in a block
//         voting or scores (when voted or can't vote)
// shows question as a topic link
// shows poll from specified topic
// shows most recent poll from specified board
//
// based on ssi_showPoll();
// added block hacks by Raysr and Thurnok from:
//    http://tpblocks.ccs-net.com/index.php?topic=25
//    http://tpblocks.ccs-net.com/index.php?topic=40
//
// usage:
// - copy whole code to phpblock.
// - at the end of the code use function
// tp_showPoll(topic number or null, 'echo' or null, board number or null)
// or
// copy the function to SSI.php
// put only the function call in phpblock
//
// examples:
// show the poll from topic 34
// tp_showPoll(34);                     
//
// show the most recent poll from the board number 5
// tp_showPoll(null,'echo',5);           
//
// keep in mind, that if board is specified, topic is ignored
// so it will display the same as above
// tp_showPoll(34,'echo',5)             
//
// put the array with poll from board 5 into $thepoll variable
// $thepoll = tp_showPoll(null,null,5); 
//
// if you call the function more than once,
// with different options, block will show more polls
// but I'm not sure if voting would work correctly :(
