Integrate with Brokers

[migueldinisdev]

Broker integrations allows to:

• show each wallet status (cash, value, some available statistics)
• show each wallet's transactions, orders, cashflows, etc.
• still let it group the assets into pies, regardless of broker/wallet

Broker integrations do not allow to:

• fetch market prices

the idea is to look into the wallets and import transactions.
