More tests and fixes resulting from such

Settings class reworked to allow easier testing

Fix to Payment.orphan() where fee was being incorrectly subtracted instead of added

Added AssetRepository.fromAssetName(String): AssetData

Fixed deleting assets from HSQLDB repository due to broken column name in SQL.

Fixed saving IssueAssetTransactions in HSQLDB repository due to missing column binding.

More TransactionTests!
