//  Author: Trabis
//  URL: http://www.xuups.com
//  E-Mail: lusopoemas@gmail.com
//  Plugin version: 1.1
//  Release date: 06-04-2009
//  Usage : just place <{block id=1}> inside any template or theme, replace '1' with the id of the block you want to show
//
//  Other options:
//  display = 'title' -> shows just title
//  display = 'none' -> renders the block but does not display it
//  options = 'enter|block|options' -> overwrites block default options
//  groups = 'enter|allowed|groups' -> overwrites block default group view permissions
//  cache = 3600 -> overwrite cache time(in seconds)
//
//  Examples:
//  <{block id=1 display="title"}>   displays just the block title
//  <{block id=1}>                   displays just the block content
//  <{block id=7 display="none"}>    does not display nothing but executes the block, this can go for online block or to trigger some cron block
//  <{block id=600 groups="0|1" cache=20}>  display block just for this 2 groups and sets a cache of 20 seconds
//  <{block id=600 options="100|100|s_poweredby.gif|0"}> displays block with diferent options
