Missing multisig-specific UI elements
Because CSP doesn't allow inline-scripts. This required getting the types for node-forge correct, too.
Requires passing the parameters in the request to ensure generation of the correct decryption key.

This PR adds two requests:
Connect
For this request, I am adding deterministic RSA key generation from the user's Key's
secret. The public RSA key is then shared with the connected app, to be able to encrypt data that only the Keyguard can decrypt again. Encryption and decryption uses thewindow.crypto.subtleAPIs.SignMultisigRequest
For this request, I am adding a WebAssembly file + JS loader, and the raw Rust code that produces it. This is needed as with the multisig scheme Nimiq is using, scalar multiplication is required, which we cannot do in Javascript. A minimal Rust crate does the trick, and is used as WASM when signing.
