Also added the hdPath that Christian had told me to our calls to the LightWallet, but this does not seem to have made us generate the same accounts as `testrpc` yet.
Added initial test just to verify we can recover the accounts we generate in this way.
Still need to add compliance test to make sure this interoperates with testrpc's new mnemonic flag.
In order to persist the seed word page until the user clicks the confirmation button, we need to store the seed words in localStorage.
To simplify this process I've also reorganized some of the account manager code, broken up one large function into many smaller functions, and created a new class for the IdMgmt object.
Again, sorry such a big refactor in one commit, but I really had to break it down to work through it.
