Translating the projectfile

[urskaufmann]

The actual projectfile has many untranslated values (e.g. in the hydraulic - vw-tables > field alias).
I think for the first version of the translation @m-kuhn did an automatic update with the values in the database. Is that much work? (manual translation is boring...)

There are also the fieldnames of vw_individual_surface missing in transifex.

@m-kuhn @urskaufmann I think this is solved - please re-open if not
