Add missing UI elements initialization for LoginDialog

[oleg-dubinskiy]

Restore an initialization of several UI elements which was previously removed. Move some initialization code to the dialog creation constructor.
Fixes LoginDialog crash when trying to login in Spotify account.
Properly fixes #43.
Here are some screenshots proving LoginDialog does not crash anymore and works perfectly now, although it looks a bit crooked, judging by the elements position (works on all OSes):
Ubuntu 21.10:

Windows XP Professional SP3:

I did not make a screenshot yet, but it works in ReactOS 0.4.15-dev as well too. 🙂
On ReactOS and Windows XP, I tested it with the following Java version: https://archive.org/details/jre1.8.0_251_XP. Much older versions (e. g., 8u51, are not working properly with this still).

The LoginDialog style is controlled by a .form file. It get's transformed at compile time:

package com.spotifyxp.dialogs;

import javax.swing.JDialog;

import javax.swing.JPanel;

public class LoginDialog extends JDialog {
private JPanel contentPane;
private JButton spotifyokbutton;
private JButton spotifycancelbutton;

public LoginDialog() {
    this.$$$setupUI$$$(); //Initialization of the contentPanel
    this.spotifyusernamefield.setColumns(10);
    this.usernamepasswordfield.setColumns(10);
    this.facebook.setText("Facebook");
    this.facebook.setEnabled(false);
    this.facebook.setToolTipText("Facebook auth not supported");
    this.facebook.addActionListener(new AsyncActionListener(new 1(this)));

    this.spotifyokbutton.addActionListener(new AsyncActionListener(new 2(this)));

    this.spotifycancelbutton.addActionListener(new AsyncActionListener(new 3(this)));
    this.spotifylabelusername.setText("E-Mail");
    this.spotifylabelpassword.setText("Password");
}

public void openWithInvalidAuth() {
    this.setContentPane(this.contentPane);
    this.setModal(true);
    this.setPreferredSize(new Dimension(350, 356));
    this.setResizable(false);
    this.getRootPane().setDefaultButton(this.spotifyokbutton);

    this.getRootPane().putClientProperty("JRootPane.titleBarForeground", Color.red);
    Initiator.past = true;
    SplashPanel.frame.setAlwaysOnTop(false);
    this.pack();
    this.setVisible(true);
    Initiator.past = false;
    Initiator.startupTime = new StartupTime();
    Initiator.thread.start();
    SplashPanel.frame.setAlwaysOnTop(true);
}

    Initiator.startupTime = new StartupTime();
    Initiator.thread.start();
    SplashPanel.frame.setAlwaysOnTop(true);
}

public static void main(String[] args) {
    LoginDialog dialog = new LoginDialog();
    dialog.open();
}

private void createUIComponents() {
    this.spotifyusernamefield = new CustomLengthTextField(254);
    this.usernamepasswordfield = new CustomLengthPasswordField(500);

}
