Modify project selection

The new project selection has two advantages:
1. It's possible to create and run e.g. projects a and aa
   Therefore it is possible to create a hirarchy again.
2. When inserting the project key only letters for valid projects are accepted.
   E.g. two projects exists aa and ab. In that case it is not possible to insert
   ac. Only a will be shown in the footer.
