GUI compilation fixes for MSVC.
* libgui/src/dialog.cc (ACTIVE_ESCAPE, RICH_TEXT): Define to 1 instead of
"true".
(LINE_EDIT_FOLLOWS_PROMPT): Define to 0 instead of "false".
*libgui/src/settings-dialog.cc (settings_dialog::read_lexer_settings,
settings_dialog::read_workspace_colors,
settings_dialog::read_terminal_colors): Use QVector instead of C99
non-constant arrays.
