Menu + console added on GUI

I have changed the theme of the GUI (now black and blue). Menu + console added.

Compatibility of those two widgets:

- Google chrome Version 30 canary, OSX 10.8.4/win 7
- Opera next 16, OSX 10.8.4/win 7
- Mozilla firefox 23.0, OSX 10.8.4/win 7
- Internet explorer 11, win7

I have noticed a bug with:

- Safari on 6.0.5 OSX 10.8.4
- Safari on 5.1.7 w7

The first menu's item is sliding down when we load the viewer, it is his default state. Here a picture showing this bug:
