bring a launch back to the board 60 days after it went live

ShipDesk.dev now lets a product come back as a relaunch 60 days after its last launch went live, with its own week, upvotes, review and payment while the first launch keeps its week, medal and results. the relaunch copies the old words, logo and pictures, locks the name and links, and still lets you add new pictures. each relaunch shows a note about what is new, links to the first launch, and gets a relaunched label on the board and launch page. relaunches are left out of best lists, alternatives and the sitemap so the same product only shows once, and launch owners get a timed invite email after 60 days.
