* Change coinbase maturity to 240 blocks in most cases, with main/test early chains allowing 30 blocks. I've kept the 240 consistent in regtest to avoid having to redesign a lot of the test cases. * Disabled mining unit test which require COINBASE_MATURITY worth of pre-calculated blocks, as we'd otherwise be constantly refactoring them. * Moved functional test which uses the Bitcoin testnet block data as its reference, as it completely breaks as we introduce Dogecoin data. * Updated standard blockchains for tests from 100/200 to 240/480 as appropriate.
