Correction: Onyx on First, Washington, DC

[Miki1993]

There are two buildings that have some of their info mixed up:

Onyx on First: http://skyscraperpage.com/cities/?buildingID=59127
100 M Street: http://skyscraperpage.com/cities/?buildingID=48618

Here are some corrections:
- The drawing I did for Onyx on First is actually a drawing of 100 M Street - I will fix the height of the drawing, which is currently ~10m too tall.
- The coordinates for 100 M Street are correct, but the coordinates for Onyx on First are actually 38.8772, -77.0055
