Fix #10 - Use a CNAME for api.3drobotics.com so we can store cookies

Important note (attn @mrpollo and @jasonshort) - for strict browser
settings (Safari) 3rd party cookies are not allowed.  Our api server is
at api.3drobotics.com, therefore any app that wants to take advantage of
the login cookie we set will need to create a CNAME under their domain
(in this case api.droneshare.com) that points to api.3drobotics.com.
API usage is through that CNAME which keeps safari happy.
