Reduce redirects

PageSpeed Insights suggests to get rid of the redirects.

dear @paulmenzel ,

actually it's an escalation of routes which causes the redirects:

domain.tld/
domain.tld/locale/
domain.tld/locale/first_menu_item

so i guess, making the init recursive, it would be possible to jump directly form domain.tld to domain.tld/locale/first_menu_item - wich reduces the redirects by 50 percent. maybe we can optimize the whole init method in ApplicationController - feel free do contribute a pull request to improve this awesome project :)
