* [syncmgr] - Add blockmode, normal mode, headermode - Add config file - Add test files - removed RequestBlocks and RequestHeaders from peers, as we will use the peermanager for this - OnHeaders and OnBlock in syncmgr, now return errors - refactored all tests to use a convenience method to return a syncmgr and testHelper
