Add Export Private Keys Option

[Efrainq07]

I would like to request an option to export the private keys of individual accounts.

I imported some ETH addresses by adding their private keys but can't retrieve them, seems kind of asymmetrical.

This is specially important for BTC addresses too.

@kvhnuke I would like to add this feature myself, could you give me some guidance or code-pointers on how I could do that?
