Successful build with tests. 
-cleaned up walletcontroller's save function. Now only stores
the mnemonic seed generated by the walletAppkit.
-We now load a wallet from a mnemonic seed.
Extend WalletController to load wallets from any .wallet file
Add to gitignore so we don't track any of the files created by running
tests. You will have plenty of your own.
Added and tested encrypt/decrypt wrappers for the wallet in our wallet
controller
