moved open/closed to base.html, so it shows on all sites; and resized it

added Facebook like box (section class 5) to index.html

moved Visit Us (new section class 6) and removed map image from index.html

created def _time() in main.py which returns if the hackerdojo is open(this was copied
from IndexHandler); This is needed for open/closed to work correctly in all sites

Resized the height of sections one through five so it fits with height of the like box; added section six in hackerdojo.css

Kept the old index.html als index-old.html
-Remove Like Button Header

- Fixed a Redirect URL for Mobile Device Lab  in main.py
