Move third party wallet import code into its own module.
Reason is KryptoKit requires 'aesjs', which adds extra 70k of code when browserified. This change could be reverted once the code can be replaced with 'crypto'.

* `fromV1(input, password)` - import a wallet (Version 1 of the Ethereum wallet format)
|

* `fromV3(input, password)` - import a wallet (Version 3 of the Ethereum wallet format)
|
||||
* `fromEthSale(input, password)` - import an Ethereum Pre Sale wallet
|

|

For the V1, V3 and EthSale formats the input is a JSON serialized string. All these formats require a password.
|

Third party imports:
|
||||
|
||||
* `fromEtherCamp(passphrase)` - import a brain wallet used by Ether.Camp
|
||||
* `fromEtherWallet(input, password)` - import a wallet generated by EtherWallet
|
||||
* `fromKryptoKit(seed)` - import a wallet from a KryptoKit seed
|
||||
* `fromQuorumWallet(passphrase, userid)` - import a brain wallet used by Quorum Wallet
|
||||
|
||||
For the V1, V3 and EthSale formats the input is a JSON serialized string. All these formats require a password.
|
||||
To use these, first import the appropriate submodule:
|
||||
|
||||
`var thirdparty = require('ethereumjs-wallet/thirdparty')`
