gateone.js:  Renamed 'termwrapper' to 'gridwrapper' everywhere.  This is to make way for the 'grid' to become workspaces (like multiple desktops) instead of just terminals.
terminal.js:  Renamed 'termwrapper' to 'gridwrapper' everywhere.  This is to make way for the 'grid' to become workspaces (like multiple desktops) instead of just terminals.
gateone.js:  GateOne.Visual.enableScrollback(), GateOne.Visual.disableScrollback(), and GateOne.Visual.toggleScrollback() have been relocated to GateOne.Terminal in terminal.js (they were terminal-specific functions so it only makes sense).
utils.py:  Added a new function:  strip_xss().  It will remove or entity-encode any HTML tag that includes a way to execute JavaScript, VBscript, or Flash nonsense.
gateone.py: The ApplicationWebSocket.broadcast() function is now using strip_xss().
HTML Plugin:  Updated with a more comprehensive whitelist to match what's in strip_xss()'.
