Move get_item_localised_name from the quality mod to core utils

[LuziferSenpai]

Hey,

the function get_item_localised_name from the quality mod is awesome, but it would be even better if it was a utils function.

Greetz,

That would force the get_prototype function to be in util and that's honestly the one I feel needs to be in there more

But yeah I do think they are simple and useful enough functions to deserve to be canon utilities

+1, i dont understand why it isn't there already

Several of my otherwise simple mods have had to define my own get_prototypes function (which retuens an array so you can either loop over everything, or get a specific prototype), so I was very surprised it's not already in utils.

I agree that this would be nice to have in lualib. In the meantime, I have added some similar things to flib for getting localised names and prototypes by base type.
