* new blooms database

* fixed conflict in Cargo.lock

* removed bloomchain

* cleanup in progress

* all tests passing in trace db with new blooms-db

* added trace_blooms to BlockChainDB interface, fixed db flushing

* BlockChainDB no longer exposes RwLock in the interface

* automatically flush blooms-db after every insert

* blooms-db uses io::BufReader to read files, wrap blooms-db into Mutex, cause fs::File is just a shared file handle

* fix json_tests

* blooms-db can filter multiple possibilities at the same time

* removed enum trace/db.rs CacheId

* lint fixes

* fixed tests

* kvdb-rocksdb uses fs-swap crate

* update Cargo.lock

* use fs::rename

* fixed failing test on linux

* fix tests

* use fs_swap

* fixed failing test on linux

* cleanup after swap

* fix tests

* fixed osx permissions

* simplify parity database opening functions

* added migration to blooms-db

* address @niklasad1 grumbles
