    entryArea: Trim newline(s)/space(s) in pasted text
    
    Remove extra newlines or spaces surrounding the pasted text
    to prevent unwanted newlines/spaces from being pasted and
    sent to pastebin.
    
    Unnecessary whitespace around the selected text is not useful
    and it usually appears as an odd behaviour when selecting
    multiline text from webpages.
