Eighth release candidate for 1.0.0

Found too many issues from the RC7 to go straight to the 1.0.0 release, so I'm doing ONE MORE release candidate. Changes since RC7 are below:

8df91f1 - fix bug in 2fa module that lost user settings after sucessfully entering the 2fa code
6c79390 - re-add accidentally removed list style setting handler
faf83de - add missing previous/next links to the combined sent view
b5964bd - fix potential race condition that could break 2fa codes because of an incorrect barcode being scanned in by the user
624a44e - add a note to the 2fa ini about keeping the server time accurate
736eed2 - test a fix for search string formatting with non-ascii chars
7fa2e62 - test a fix for subject encoding problems
