Clear screen after folder initialization.

[godaygo]

Currently you see all logs with folder switching when you start a terminal, maybe it will be better to clear screen after initialization (in addition, this currently working directory is visible in prompt). Command clear is suitable for almost all consoles (?), and only cmd uses cls.

I am unfamiliar with JS :) And did this as follows:

    var clearCommand = "clear";                                  // <--- Here
    var dir = path.dirname(uri.fsPath);
    var terminal = vscode.window.createTerminal();
    terminal.show(false);
    switch (kindOfShell(vscode.workspace.getConfiguration('terminal'))) {
        case "wslbash":
            // c:\workspace\foo to /mnt/c/workspace/foo
            dir = dir.replace(/(\w):/, '/mnt/$1').replace(/\\/g, '/');
            break;
        case "cmd":
            // send 1st two characters (drive letter and colon) to the terminal
            // so that drive letter is updated before running cd
            clearCommand = "cls";                                // <--- Here
            terminal.sendText(dir.slice(0, 2));
    }
    terminal.sendText("cd \"" + dir + "\"");
    terminal.sendText(clearCommand);                             // <--- Here

I can open a PR if this seems reasonable for you.

There's now a cwd property in the terminal API, the extension should be made to use that (WSL may still need a cd though).
