Cutscene/video mode hotkey

[Histidine91]

As per http://zero-k.info/Forum/Post/177107#177107

It should do the following when pressed, and revert to the original state/settings when pressed again (or the widget shuts down):

• Hide UI (F5's hideinterfaceandcursor)
• Icon distance 1000
• Set Always Draw Commands to require Shift
• LOS, metalmap, etc. view off
• Disable chat notification sound in chat widgets
• Possibly some other stuff I forgot

Set Always Draw Commands to require Shift

Perhaps it's better with never show - shift has camera uses.
