#554000 by killes: Preview checking wrong flag for preview state causes feeds to display incorrectly when embedded.

#512650 by sdboyer: Multiple many to one arguments on the same relationship were not relationship safe.

#540122 by stella: Attachment displays should attach even if arguments caused the primary display to abort.

#546586 by dww: Fixed bugs that prevented '0' being a valid rewrite text or empty text for a view field. Also fixes a logic bug regarding the handling of the 'Count the number 0 as empty' setting.

table was broken so only the final field would display.

format_size() was called on it twice.

CHANGELOG whitespace cleanup by accident. Not off to a good start. ;)

Tables would not accept 0 as having data so columns with zeroes would lose data when merging with other columns.
