Most SQL tables defined but only payment transactions actually implemented. Maven support added. Some code imported from 'old' Qora: RIPEMD160 renamed as BrokenMD160 and deprecated. whispersystem's Ed25519 implementation (to be replaced with bouncycastle). Basic Account/PublicKeyAccount/PrivateKeyAccount code. Some utils like Base58 and Pair. To use: Use maven to fetch dependencies. Build project. Fire up an old-gen Qora node. Run src/test/update.java as a JUnit test to build DB structure. Run src/test/migrate.java as a JUnit test to migrate old Qora blocks to DB. You should now be able to run src/test/load.java and src/test/save.java as JUnit tests demonstrating loading/saving Transactions from/to database. This commit done while halfway through adding Block support!
