If your block is returning formatted content or provide files for download, you should override this method to use the
external_format_text, external_format_string functions for formatting or external_util::get_area_files for files.
See block_html as example.
* External functions core_block::get_course_blocks and core_block::get_dashboard_blocks have a new parameter to indicate if
you want to receive the block contents.
