Easy SSH 0.4.3

Fixed

• New connection: the Host step accepts what you'd type after ssh, such as deploy@10.0.4.12:2222 or [fe80::1]:2200, and fills in User and Port from it. Before, the whole text was saved as the host name and the connection could not work.

Changed

• A smaller, faster-loading extension: the bundle leaves out ssh2's SSH server and key generator, which Easy SSH never uses, and targets the Node.js version that VS Code 1.74 ships.
• README brought in line with current behaviour.
