Bugs while uploading roms

There are permissions problem on 4 directories : mupen64 and scummvm roms, retroarch bios and videos folders.

To correct that do the following :

$ mkdir /home/pi/retro/roms_scummvm
$ chmod 777 /home/pi/retro/roms_scummvm
$ chmod 777 mupen64plus/roms/
$ mkdir /home/pi/retro/bios
$ chmod 777 /home/pi/retro/bios
$ chmod 777 videos/
$ sudo /etc/init.d/samba restart

The roms should be uploadable. I changed that in the current release and re uploaded it.
