[General] Wiki web name for EngineeringArea

[Jared Rhine]

The EngineeringArea is due to be pushed out as a new chandlerproject.org 
wiki area, at the same level as "Product" and "Teams".

There are a couple options for the specific name to be used. 
"EngineeringArea" is due to become "DevelopersArea", which suggests 
"Developers" as wiki web area name.

But "Develop" is shorter, and does not overlap conceptually with "Teams".

"Development" is also an option.

PPD are the drivers for the wiki taxonomy, but anyone is welcome to 
chime-in.

Right now, I personally favor "Develop" for its brevity, but it doesn't 
feel perfect.
