* use bloomchain crate in blockchain module. remove obsole chainfilter submodule * update database version to 6.0 * removed redundant line * simple db migration * make migration slightly more functional * bloomchain migration * migration version is just a single unsigned integer * updated migration v6 * parity migration * db migration * removed hardcoded migration dir * replace ptr::copy with clone_from_slice, removed potential endianess problem from trace/db.rs * removed superfluous line * blockchains log blooms config is not exposed any more
