Refresh content List in Dev Mode

[Tubers]

I would love a feature where once you added cars and tracks into the packs folder or main Re-volt directory (why do we do that beats me ), it would be cool if there was a refresh key to refresh the content on.

I would like to add a similar suggestion: Having the possibility to delete content (cars, tracks, cups, maybe skins) directly inside RVGL by using the delete key would be also pretty useful.
