Split the process_elements function to: * process_node_to_plain_text_for_exporting * process_node_to_plain_text_changing_composer_mode * process_node_to_html_changing_composer_mode * process_node_to_html_for_exporting that process the given nodes (usually just BODY) for purposes described by the function names - i.e. the first function will process the BODY and will transform the lists to their plain text version, fill the indentation or alignment with spaces and so on; the process_node_to_html_for_exporting will remove all the classes, ids and other attributes from the DOM. Also in the process_node_to_plain_text_for_exporting correctly process the block elements to avoid situations when an extra new line could be added on the end of the block or not added at all. Always look if the new line is indeed there, if not add it there explicitly. This fixes the bug 767681. Also avoid working with the innerHTML of the BODY (that was previously leaked), but instead copy the nodes. Also remove images from the BODY if they are presented to avoid unneeded line break. After this change the indented elements will be preserved when switching between composer modes. When removing an image also remove its wrappers and the block where the image was, if the block is empty after the image was removed, otherwise an extra line will be added to the output.
