Update main.geojson for new markers in DECC

[mmdolbow]

Putting this in a pull request instead of commiting directly to pages, because 1) the new data doesn't fit the scheme 2) I'm not sure the styling will work well with all these additional points 3) it might look a bit cluttered if the styling does work and 4) then again, it might break entirely! :-)

So, I'm not a huge fan of the look since it adds a bit of clutter... here's what it looks like on load:

As you mentioned, it doesn't follow the current structure, so the popup looks a little odd...

That being said, I'm not opposed to adding it in, but what would you think of the following methodology instead?:

1. Use a polygon style instead (it could be deccLayout.geojson, or an entirely new file as well).
2. Break out the regions of the DECC using the polygon.
3. We add it to the map by grouping it with the main.geojson file (and add those layers as checkboxes, instead of the current radio button)

... Thoughts? /cc #5

I like the idea of having a separate check box or a scale dependency to toggle these details - they're only pertinent when zoomed way in, and only when someone wants to know. We can certainly do polygons, although that's more complicated. Another option would be points with much smaller icons so they are less distracting. Your call, I will execute as desired. Final question: should we have separate layers for the different floors, or one layer where the floor is identified in the properties?

[mmdolbow]

As resolved in discussion: I will make two new layers of polygons, one for each floor, and commit to the master.

Thanks! Closing this PR since we are going in a different direction. Looking forward to those geojson's!
