Adds "Rate on OMDB" button on osu! beatmap pages
Adds a button on osu! beatmap pages that links directly to the beatmap's respective page on OMDB (https://omdb.nyahh.net/).
Button should take a second or two to show up.
If you are having issues getting this to work, contact me on Discord: cyndifusic#9323
