v0.8.5-rc.1 Release candidate for v0.8.5. Major differences: - Replaced TUI (termnal screen interface drawing) with new code that makes sure out of bounds accesses are as little as possible. Also every area of a screen holds provenance; you cannot mix area/region information of different screens (virtual or tty). Every time there is a window resize, the screen's generation gets refreshed. - Fixed some imap flag sync issues. - Many small refactors across all the codebase.
