Tested/fixed delta calculations

Browse Source 
Tests now use a fixed delta of 0.5 to make sure calculations work with deltas different from 1.0

/**
* Tests code related to the power system in general, but not specific blocks.
* All tests are run with a fixed delta of 0.5 so delta considerations can be tested as well.
* Additionally, each PowerGraph::update() call will have its own thread frame, i.e. the method will never be called twice within the same frame.
* Both of these constraints are handled by FakeThreadHandler within PowerTestFixture.
* Any power amount (produced, consumed, buffered) should be affected by FakeThreadHandler.fakeDelta but satisfaction should not!
