Persist blockchain with leveldb on disk (#48)
* Created test_data folder with block json files for testing + create separate file for block base.

* Fixed bug in WriteVarUint + Trim logic + unit tests

* Refactored store and add more tests for it.

* restore headerList from chain file

* Fix tx decode bug + lots of housekeeping.

* Implemented Node restore state from chain file.

* Created standalone package for storage. Added couple more methods to Batch and Store interfaces.

* Block persisting + tests

* bumped version -> 0.31.0
