Link color configuration not completely implemented

[aadjemonkeyrock]

With the color configuration I can set a link color. This works fine, except in the checkmark when you select images in the album. This checkmark always uses the default link color.

This can be seen in AssetCollectionViewCell.swift on line 65

• iconView.tintColor = TatsiConfig.default.colors.link

This is either forgotten or skipped because in the AssetCollectionViewCell you don't have access to the configuration.

I really needed this for my project and I implemented an additional custom color. I've created a PR for the issue too, in case you are interested.
