ch01-bankapp-xml has extra unnecessary methods in FixedDepositDao

[NutterzUK]

These methods make it a little bit more tricky to see exactly what is going on. For chapter 1, I recommend in FixedDepositDao these be removed:

	public static FixedDepositController xyz(String xyz) {
		System.out.println(xyz);
		return new FixedDepositController();
	}

	public void setUrl(String url) {
		this.url = url;
	}

	public void setDriverClass(String driverClass) {
		this.driverClass = driverClass;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public void setPassword(String password) {
		this.password = password;
	}

At this stage I have no idea why the Dao would want a static method to create a new FixedDepositController, or why it is called xyz.
