Bulk product updating

[KeithM1]

Allow users to update products in bulk directly in ShipStation instead of having to do so individually or without having to import or export a CVS file to do so. We can update products individually within ShipStation so having the capability to update several products at once would be super convenient. I have several products that I'd like to update the weights and it would be nice to be able to do so in ShipStation simply by selecting multiple products and having columns appear where I can easily copy and paste the updated weights instead of doing it by clicking each product individually which is very time consuming.
