(Feature Request) Add option for a roms manuel.

[DanielLester83]

I'd like to see a "View Manual" line added to the individual roms 'options' pop-up box, as well as a "manual" text box in the 'edit metadata' pop-up box for the file path.

I'm proposing that the manuals should be in a .cbz like format of sequential images in a zip file.

I imagine that Emulation stations code can already handle unzipping and displaying images, but for convenience sake I'll post how I have already gotten it to work with fbi on retropie. The $1 = the passed file path.

/opt/retropie/supplementary/runcommand/joy2key.py /dev/input/jsX 0x4A 0x20 0x2B 0x2D 0x50 0x51 0x48 0x49 & base=/tmp/manual mkdir $base /bin/tar -xf "$1" -C $base find $base -iname *.PhotoCD -or -iname *.jpeg -or -iname *.jpg -or -iname *.ppm -or -iname *.gif -or -iname *.tiff -or -iname *.xwd -or -iname *.bmp -or -iname *.png -or -iname *.webp > $base/Slideshow.list /usr/bin/fbi -a -P --noverbose --fitwidth -l $base/Slideshow.list rm -r $base sudo killall joy2key.py
