[ticket/14950] Add possibility to delete a template block
Adds a new mode to alter_block_array to allow for the deletion of a certain block of template variables. The selection method is the same as for the other modes for alter_block_array. The passed in vararray is ignored, and an out of bounds index is considered an error. PHPBB3-14944
