implemented an admin/ page. This is using the iron-router package and thus needed a newer meteor version than before. Some tweaks to both the admin and user page are made. To modifiy an exisiting database two new fields need to be saved to the collection: 'active' and 'ptab'
added missing euro-coin file
refined the stats output at the top of the admin page
