API server in master is not building

When I run the install script, I get an error when it's building the API server:

311-api    | RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd
311-api    | Traceback (most recent call last):
311-api    |   File "bin/api_start.py", line 24, in <module>
311-api    |     import app

311-api    |     import control.route_handlers as R

311-api    |     import pysupercluster
311-api    | ImportError: numpy.core.multiarray failed to import

The version of numpy that's in the API's requirement.txt is too old. We should be able to upgrade it and get past this build error.

We're not using the server in master anymore, so let's not fix this.
