ola 0.9.0 (new formula)

Add formula for the Open Lighting Architecture, which is "a framework
for lighting control information. It supports a range of protocols and
over a dozen USB devices. It can run as a standalone service, which is
useful for converting signals between protocols, or alternatively using
the OLA API, it can be used as the backend for lighting control
software. OLA runs on many different platforms including ARM, which
makes it a perfect fit for low cost Ethernet to DMX gateways."
