option to show TT news

* Added css to web_accessible_resources in manifest.json 
(so that it's possible to load it via chrome-extension://CHROME_ID/css/libdeluxe.css)

* IconBar added (only for the news icon so far, could maybe add options to change the layout here later)

* show/hide news on click

* header h1 pointer-cursor added and reduced clickable area

Note: might want to change that news-icon. also not load it via imgur, like now. D:
