New features overview: * Unicode. User interface handles multi-column characters. API can handle char* like a multibyte character string. Internally wide characters are used for keyboard input, to adapt word wrapping and dynamic text auto-sizing for multi-column characters. * Forms refactoring. Complete rewrite deleting libformw dependency. * Theme. New utility options to save and load custom theme at run-time. * TUI navigation. Added keys to navigate input components. Changed default focus behavior of input dialogs to be LGPL-dialog-like; a new option can set the previous whiptail-like behavior. See /usr/src/contrib/bsddialog/CHANGELOG '2022-08-29 Version 0.3' for more detailed information. Merge commit '2c9fd7655ba54e7239f528e1af9fe09662de9b03'
