Changes in page's flow (routes, recruit action in home controller)

Created „recruit” view for home#recruit controller (which is handled in
routes as „/manifest”), into which not logged users will be
automatically forwarded.

There should be some basic info about the game, etc. (amongst with
login and register buttons). #tobefilled

Also modified routes to make them more humanish. (/home/Index ->
/index, /home/recruit/ - > /manifest).
