* Eliminate string arguments to OPENTEXTSTREAM #666
Empty string replaced by NIL, mostly. Otherwise, string wrapped in OPENSTRINGSTREAM. TEDIT hasn't yet been modified, just all the callers.
* INDEX, NGROUP: move to obsolete #667
* HELPSYS: Add proper FILETYPE property
* ROOMS files: Also updated for TEDIT string arguments
* TEDITMENU: menus don't grow vertically on reshaping
* CLSTREAMS, EDITINTERFACE: Update filemap for FUNCTIONS
Needs to be done for most CL-function containing files.
* Upgrade TEDIT to LF
Fixes the black boxes in the Tedit menus.
TEDIT had a built-in bias towards CR in files and in displaying them. I changed the bias to LF.
* TEDITDCL had no content
Its COMS specified lots of records etc from other TEDIT files, but none of those were actually in the symbolic file (the LCOM was OK). I loaded all of the other TEDIT files and remade/recompiled this, looks like it captured everything
