Fixes#791
It was possible for two requests to have the same ID, causing a crash and loss of StreamProvider connection.
This new id generation strategy creates a random ID, and increments it for each request.
In case the id generator is included from two different processes, I'm initializing the counter at a random number, and rolling it over a large number when it gets too big.
Our gas price buffering logic had a bug, because bn.js has inconsistent behavior when using hex-prefixed output. The issue has been opened with them here:
https://github.com/indutny/bn.js/issues/151
We've corrected our usage in the mean time.
This contract hex does include the value `f4`, but it was compiled from a contract with no instance of `.delegatecall`. I believe `f4` in this case is part of some other value or contract address, and `ethBinToOps` has some error in how it skips pushed data.

SubmitPassword was not creating a new id-management
This is because I broke up the old "createIdmgmt" method to not perform as much conditional logic.
Now the pieces are reusable and do what they should do.
Fixed bug where the second new vault created in an IdStore would initially return the accounts from the original store.
Also fixed some tests that were incorrect.
eth-lightwallet was previously not salting vault passwords, potentially making it easier to crack them once obtained.
This branch incorporates the API changes to allow us to take advantage of the new salting logic.
This is still throwing deprecation warnings, but that's actually a bug in eth-lightwallet I wrote, [I've submitted a PR for that here](https://github.com/ConsenSys/eth-lightwallet/pull/116).
