0.5.0

Release notes

• BREAKING:
  • New api methods, some fields are removed/partly moved to another place due blockchain api has been changed.
• Fixed conversion from double to BigDecimal - now only through the string. Don't do this: new BigDecimal(0.1d) - it leads too much garbage
• Added support for new types of transaction:
  • Create multisig address (transaction for creating multisignature address)
  • Multisend (single transaction for sending coins to multiple addresses)
  • Edit candidate (transaction for editing existing candidate)
• Added missing endpoints and repositories
• More tests (still without mocks. Soon...)
