Scraped when uploaded

[MaxCorpEnjoy]

Nice feature (but some work) would be to have an option to scrap the data and update the gamelist.xml when we upload a new rom.
If we assume we use a computer to upload the rom, using some javascript could maybe fasten the operation for a big set of roms.

Scrapping using Javascript ? So requesting the db api (if any?), well sure it's some big work to do.

Maybe in future, for now it's a too big feature to do it before 1.2.0 milestone, also it seems the recalbox team think about changing the scrapping technic, so we should wait it's more stable.
