sketching out the window handling API

The following files have window handling:
(find . -type f | xargs grep -s -l -i '<script' | xargs grep -s -l -i '\.open')


things that refer to loncapaclient
find . -type f | xargs grep loncapaclient

# ./loncom/html/res/adm/pages/menu.html

function windowcheck() {
   if (clientwindow.closed) {"http://"+clienthost+"/"); 

function logout () {
   if (clientwindow.status!='MenuControl:nologout')

The way that children windows of 
loncapaclient should work:

* need to track if they have ever been opened
* if not,
   * open when needed
   * never refer to any object properties
     * which also means never close
* if currently open,
   * just focus when needed
   * close when needed
   * can refer to object properties
* if have been closed,
   * can refer to object properties

The way loncapaclient window "should" work.
* lonxml makes exceptions for some URI=resources like
 * /res/adm/pages/menu.html
 * bookmark stuff.html
* lonxml should by default
 * a script command should follow the body tag
   * name the window (loncapaclientURICHECKSUM)
   * tell remote control it exists
   * remote control checks clientwindow (opener)
     and if is loncapaclientURICHECKSUM
     it changes this to loncapaclient

window instance <-- invoked from menu.html, but can be referred
                    to from other children windows
  + status (has it ever been opened, is it closed, is it open)

create_window_dependency(base,offshoot) <-- "offshoot" window
                    should only be open if "base" window is open
