New method added block_base::get_content_for_external().
It will return all the block contents rendered for external functions.
If your block is returning formatted content or provide files for download,

external_format_string functions for formatting or
external_util::get_area_files for files.
See block_html as example.

parent context, it was inheritting from its parent context _level_ which
is just wrong.
