[Enhancement] Make it less easy to delete links by accident

[jwmanly]

Currently, the delete "x" icon is relatively close to the quick link itself and VERY close to the "local/global" icon. This is dangerous, as the clicking the "x" just triggers a delete without any further confirmation from the user. I would suggest either:

a) An option to have the delete "x" icon trigger some kind of "Are you sure?" dialog before actually deleting the link, or

b) Failing that, have an option available in the extention "Gmail Quick Links" details settings page to turn off the "x" icon entirely. A user who used this who later wanted to remove one or more links would have to turn the setting back on before they could do so, but that seems like a reasonable trade vs. deleting quick links by accident with no confirmation or way to "undo" the action.
