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'. 

Instead of combining Saves by emulator, can we keep these seperate for readability? If we change emulators, then this struture will be less obscure
