improves the gradle tasks for copying the maps and translations

Instead of copying the files to the normal res folder they get copied
to the build folder, which gives the user the hint that they are
generated and should not be edited in this location.

> **Warning**
After pulling this commit both folders '/app/src/main/res' and 'app/src/main/assets'
should be deleted if they exist, since they are no longer ignored (since they don't get used anymore)!
