state saves linked to RetroRig folder / disabled error prompt during scraping in RCB / dolphin 3:4.0.0.3

*state saves linked to RetroRig folder*

Links for the main emulators mednafen, mupen64plus, dolphin, ppsspp, pcsx2 and gens. All backup worthy files should now reside in folder `RetroRig`. To make testing easier with different operating systems, I've created a data partion with `ROMs`, `BIOS` and `Saves`.

*disabled error prompt during scraping in RCB*
Sometimes I got the error message "can not create artwork file". It was prompting for a user input, thus stopping the download process. I've just delete the prompt, a log entry will still be created.

*dolphin 3:4.0.0.3*
Patched to raise it's graphics window to the front after one second being in fullscreen mode. This was only an issue  with window manager 'Mutter'.
