Fix: secutiry

[StephanUnfried]

HTMLClient:

1. Change die top navigation (My Profile My Contexts My Resources My Groups) from a window.location model to a model that supports headers.
   /server/src/main/resources/webcontent/js/navigation.js
2. When navigating add the authentication token to the header: headers : {"Authorization" : localStorage.getItem("token"),}
3. In the corresponding rest interfaces and their corresponding helper classes use the token to identify the user and authenify him.
   org.openape.ui.velocity.controller.[name]
   org.openape.ui.velocity.requestHandler.[name]
   For authentication use our auth service
   /server/src/main/java/org/openape/server/auth/AuthService.java
4. change the direct Database access, through DatabaseConnection.java, to a route through the usual rest interfaces. A get on the root path of each context rest interface returns a list of all (owned and public) contexts.
