de_CH ready for 4.6 dryrun

Just wanted to let @soean and @timse201 know that I rejected one string for #de_CH 4.6 not because I don’t like them, but because we’re not translating directly in de_CH, but only in de_DE. All changes for de_CH are derived from de_DE and adapted by a semi-automatic updated script. More information can be found on https://github.com/openstream/wordpress-de-ch.
