Remove newline from Done progress message

[HebaruSan]

Problem

I may be the only person bothered by this, but if you install mods in GUI, at the end the label above the progress bar says "(Done!" without a close parenthesis:

(I think you may even be able to see some of the rest of the message wrapped onto the next line in Mono.)

Cause

There's a "\r\n" in the RaiseProgress message at the end of the install flow:

CKAN/Core/ModuleInstaller.cs

Line 235 in e5fc437

User.RaiseProgress("Done!\r\n", 100);

GUI inserts this string into the middle of a larger formatted string, which is then split in half at that point:

CKAN/GUI/GUIUser.cs

Line 40 in e5fc437

Main.Instance.SetDescription($"{format} - {percent}%");

CKAN/GUI/MainWait.cs

Lines 99 to 102 in e5fc437

	public void SetDescription(string message)
	{
	Util.Invoke(MessageTextBox, () => MessageTextBox.Text = "(" + message + ")");
	}

The newline was probably included to make installing via CmdLine look better.

Changes

Now that newline sequence is removed and the close parenthesis appears:

A newline is added to the CmdLine install code to make it look the same as before.
