Add embed endpoint

[NoodlesDev987]

Hello, could you create endpoint that will create embed like this (it should be configurable)? It is possible using META OG tags.

This might be added in the future version. Currently am rewriting this into a new format which includes a full split of the back end and front-end to keep the code cleaner and even make some of the functions faster. With this change you will have to re-setup the app but it's well worth it for a much more stable app.
