Change quotes to single quotes, Header buttons should always be small, some language rewording and formatting.

BHV-11211 Modify HeaderSample to cover removed icons.

Good work David. My alterations just look like a lot because I changed the quotes to match our new coding style, which altered EVERY line. Additional changes: Header buttons should always be small, some language rewording and formatting.
