enabled easy blocks for Scaling Test Network

changed max message size to 128MB to accomodate big blocks
updated chain download tests to only download headers, not entire blocks
fixed error in chain download tests where mockTime set by previous test was interfering - needs a better solution
added chain download tests for Scaling test network
