/**
* Change already assigned key variable pair (one-dimensional - single loop entry)
*
* An example of how to use this function:
* {@example alter_block_array.php}
*
* @param string $blockname the blockname, for example 'loop'
* @param array $vararray the var array to insert/add or merge
* @param mixed $key Key to search for
*
* array: KEY => VALUE [the key/value pair to search for within the loop to determine the correct position]
*
* int: Position [the position to change or insert at directly given]
*
* If key is false the position is set to 0
* If key is true the position is set to the last entry
*
* @param string $mode Mode to execute (valid modes are 'insert' and 'change')
*
* If insert, the vararray is inserted at the given position (position counting from zero).
* If change, the current block gets merged with the vararray (resulting in new key/value pairs be added and existing keys be replaced by the new value).
*
* Since counting begins by zero, inserting at the last position will result in this array: array(vararray, last positioned array)
* and inserting at position 1 will result in this array: array(first positioned array, vararray, following vars)
*
* @return bool false on error, true on success
* @access public
