Notifications - GUI shows html tags (bullet list)

How to reproduce

• Create an info course element
• Create info message
• Type one - enter - two - enter - three (NO enter)
• Mark the words one two three and check the list formatting in the editor
• The words now display in list form
• Save the info message and close wizard
  => Message appears as escaped HTML

The same does not happen when after three an enter is added. This will add a p tag to the editor.

The problem is that the method to detect HTML only checks for some HTML element. The method is called in InfoDisplayController.createInfoMessageForDisplay().

From StringHelper class:

	public static boolean isHtml(String s) {
		if (s == null) return false;

		return s.contains("<html") || s.contains("<body") || s.contains("<p") || s.contains("<span");
	}

The method should be more robust and detect more HTML elements or maybe rewritten to return true when the first non-white character is a "<" character.
