Adding government proposals and points

 - Skipping 'skrivelser'
 - Some ministries cannot be identified by abbreviation
   - The field 'organ' in 'dokument' for 'prop' sometimes contains full
     name of ministry
   - Sometimes a non-existing abbreviation such as 'KUD t.o.m. -04'
 - There may be duplicates of (both member and government) proposal points
   and/or signatures
