Add help button to transient popups

[MichaelVyverman]

• [ ] Add span with "fa fa-question-circle" to the TransientPopup
• [ ] Give it the SWXTransientHelpBox css class
• [ ] Put the correct css right in case of scroll bar
• [ ] Add the function to open help on click
• [ ] Only add if the settings provide a help id
• [ ] Update less file to include the CSS class. Make CSS right = 20px (2 + size of closing icon)
• [ ] In MR code or other applications, also update the css to update the color (use AXMButtonHelp and provide opacity, color, background color, text shadow, and hover opacity)
