returns a reference to the first block of the given type encountered and
optionally closes all blocks until it finds it

this is mainly used by {else} plugins to close everything that was opened
between their parent and themselves

@param string $type the block type (name)
@param bool $closeAlong whether to close all blocks encountered while going down the block stack or not
@return &array the array is as such: array('type'=>pluginName, 'params'=>parameter array,
'custom'=>bool defining whether it's a custom plugin or not, for internal use)
returns a reference to the first block of the given type encountered and optionally closes all blocks until it finds it
