Fix strings in commands

timecode.cpp -- Fix file types names
video.cpp -- Fix descriptions of "video play" commands: "video/play" -> fixed grammar; "video/play/line" -> made description slightly more verbose to prevent it from fetching translation from "audio/play/line"'s STR_DISP (or STR_MENU, idk) 
vis_tool.cpp -- Remove suffixes from visual vector tools
