Add Bitcore support, Add German translation

[chill117]

Hello and thank you for taking the time to create a pull-request. I have a few notes:

• Can you split the German language translations into a separate pull-request? We will review and merge it separately.
• It is necessary to add new coins to the ct-api-server project also - otherwise the CryptoTerminal app will only show the QR code but never know when a payment was received. In the case of bitcoin and litecoin, the app subscribes (via websockets) to a channel for a payment address. When a transaction is received at that address, the transaction data is sent to the app. The ct-api-server is listening to bitcoind and litecoind nodes, receiving a stream of new transactions. So to support a new coin, nodes for that coin would need to be setup and configured with the ct-api-server.
• package-lock.json - I don't think any dependencies were added with this PR, but there are many changes to the package-lock file. I think this might not have been intended.

• Yes sure, I will plit the German language translations into a separate pull-request.
• It is necessary to add new coins to the ct-api-server project also. Is there a description to add new coins to ct-api-server project. Or do you provide me a example commit/pul-request in which way it must be added.
• Oh, sorry. I run "npm audit fix" after npm installation warnings. I will remove my changes on this file.

I am not sure what capabilities the bitcore node software has, because I am unfamiliar with that coin. So I cannot guide you on the integration process very much.

The key parts of the ct-api-server that you will want to look at are here: https://github.com/samotari/ct-api-server/blob/0674397464962132039f1907501f905539b32216/sockets.js#L157-L175
