Fix bugs #3640, 3631, 3630, 3628. Menu buttons eliminated when viewing directories in iCSTR in remoteless mode. Directory position and selection now directly below top menu bar. Directory location larger font, headings for directory options (remoteless only) smaller font. Certain directory actions directed to top, (to escape frame), to avoid nesting frames.
