[Improvement] Server-side algo compatibility check

[electroape]

Check for whether an algo you push to the client is supported on it's version or not. Don't push if not supported, show error message.

Good idea, but i currently dont know how this can be easily integrated.. The ".json" file is actually just processed as text and fille in the clientConfig for each miner and the server is not aware of version capabilities.

Store configs and templates in a memory data structure ?
