CHANGED: moved hsqldb-r5836.jar to local maven repository to fix build

HSQLDB issue, resource leak prevention, v1 differences

HSQLDB v2.4.0 had some issue with non-padded, case-insensitive string comparisons.
This is fixed in svn r5836-ish of HSQLDB but yet to be pushed out to new HSQLDB release.
So this commit includes hsqldb-r5836.jar and modified pom.xml/.classpath for now.

No need for duplicate, hidden creatorPublicKey in CancelOrderTransactionData,
CreateOrderTransactionData and CreatePollTransactionData.

Various changes to use more try-with-resources, especially with JDBC objects like
Connection, Statement, PreparedStatement, ResultSet.

Added loads of missing @Override annotations.

Fixed bug in Asset exchange order matching where the matching logic loop
would incorrectly adjust temporary amount fulfilled
by the "want" asset amount (in matchedAmount)
instead of the "have" asset amount (in tradePrice).

Disabled check for duplicate asset name in IssueAssetTransactions for old v1 transactions.

In HSQLDB repository we now use ResultSet.getTimestamp(index, UTC-calendar) to make sure we
only store/fetch UTC timestamps. The UTC-calendar is made using static final TimeZone called
HSQLDBRepository.UTC.

To keep asset IDs in line with v1, Assets.asset_id values are generated on-the-fly in HSQLDB
using a "before insert" trigger on Assets table. Corresponding code
calling HSQLDBRepository.callIdentity() replaced with SELECT statement instead.

Moved most of the HSQLDB connection properties from the connection URL to explicit code in
HSQLDBRepositoryFactory.

Fixed incorrect 'amount' lengths in PaymentTransformer, as used by MultiPayment and Arbitrary
transaction types.

Added support for mangled arbitrary transaction bytes when generating/verifying a v1 transaction signature.
In v1 Arbitrary transactions, bytes-for-signing are lost prior to final payment (but only if there are any payments).
Added corresponding code for multi-payment transactions in the same vein.

Initial stab at migrating to HSQLDB for Qora gen2

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.
