[Therion] Declination and the cs command

[Stacho Mudrak]

When trying to implement new feature we have figured out in literature,
that declination against grid north is called "needle deflection". Is this
english term, OK? It means, instead of declination, you would specify

needle-deflection 10 deg

In Slovakia, we call it  "magnetic deflection". Or may be just

declination-north grid

would be sufficient. Any comments?
