Initial stab at migrating to HSQLDB for Qora gen2

Browse Source 
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!

Notes on implementation strategy:
Using schoolbook multiplication.
Karatsuba would save a little in some cost models.
Most multiplications by 2 and 19 are 32-bit precomputations;
cheaper than 64-bit postcomputations.
There is one remaining multiplication by 19 in the carry chain;
one *19 precomputation can be merged into this,
but the resulting data flow is considerably less clean.
There are 12 carries below.
10 of them are 2-way parallelizable and vectorizable.
Can get away with 11 carries, but then data flow is much deeper.
With tighter constraints on inputs can squeeze carries into int32.

Preconditions:
|h| bounded by 1.1*2^26,1.1*2^25,1.1*2^26,1.1*2^25,etc.
Write p=2^255-19; q=floor(h/p).
Basic claim: q = floor(2^(-255)(h + 19 2^(-25)h9 + 2^(-1))).
Proof:
Have |h|<=p so |q|<=1 so |19^2 2^(-255) q|<1/4.
Also have |h-2^230 h9|<2^231 so |19 2^(-255)(h-2^230 h9)|<1/4.
Write y=2^(-1)-19^2 2^(-255)q-19 2^(-255)(h-2^230 h9).
Then 0<y<1.
Write r=h-pq.
Have 0<=r<=p-1=2^255-20.
Thus 0<=r+19(2^-255)r<r+19(2^-255)2^255<=2^255-1.
Write x=r+19(2^-255)r+y.
Then 0<x<2^255 so floor(2^(-255)x) = 0 so floor(q+2^(-255)x) = q.
Have q+2^(-255)x = 2^(-255)(h + 19 2^(-25) h9 + 2^(-1))
so floor(2^(-255)(h + 19 2^(-25) h9 + 2^(-1))) = q.

* Typical use-case scenarios:
*
* 1. Loading a Block from the database using height, signature, reference, etc.
* 2. Generating a new block, adding unconfirmed transactions
* 3. Receiving a block from another node
*
* Transaction count, transactions signature and total fees need to be maintained by Block.
* In scenario (1) these can be found in database.
* In scenarios (2) and (3) Transactions are added to the Block via addTransaction() method.
* Also in scenarios (2) and (3), Block is responsible for saving Transactions to DB.
*
* When is height set?
* In scenario (1) this can be found in database.
* In scenarios (2) and (3) this will need to be set after successful processing,
* but before Block is saved into database.
*
* GenerationSignature's data is: reference + generationTarget + generator's public key
* TransactionSignature's data is: generationSignature + transaction signatures
* Block signature is: generationSignature + transactionsSignature
