* Add bloom filter to tx receipt * wip tx receipt logs to be tested * Added Bloom - Height Mapping * keeper.go sets <height:bloombits> * keeper.go gets <height> --> bloombits * updating and querying bloom by block (to be tested with real logs) * fix bug with contract address return * added error handling instead of logging
