terminal.js:  Fixed a bug where--depending on the circumstances--mousing over an image would not keep the pastearea hidden.
terminal.py:  Improved handling of multipl simultaneous concatenated images.  This should resolve issue #287 (https://github.com/liftoff/GateOne/issues/287).  For real this time!
terminal.py:  Improved handling of images when the terminal has not scrolled enough yet for the full image to be displayed.  It will now perform some wiley list popping trickery to make images appear in a natural fashion so they always show up fully within view.
terminal.py:  Fixed a bug where the original image file was being served up in an incomplete fashion due to a missing call to flush().
