34s / 31s emulator new display

[pascal_meheut]

Hi,
I've planned to integrate it but encoutered a few issues & questions:
- I'm on holidays so it will have to wait till I'm back and have some free time
- should I replace the current one with the new one as it is better or have both?
- I cannot compile the emulator yet as supports only Qt4, not Qt5. But Qt4 is not supported anymore on recent versions of OSX at least... Some work to do here
- I do not really need to recompile the emulator to add the new skin but I would prefer to update it in the process...

So we will have to wait a few days or weeks till everything is ready.
