String formatting to preserve indentation format for HTML without use of escaping characters

A new feature added that converts String to preserve indentation formatting for html without use of escape characters. It converts a String in such a way that its spaces are not modified by HTML renderer i.e. it replaces regular space characters with non-breaking spaces known as '&nbsp;' but they look in your source as regular space ' ' and not as '&nbsp;' It also replaces new line character with '<br>'.
