Create confirmation screen for sending transaction

[TJ-BitCanna]

According to the UX flow we wanted for sending a transaction:

• put in the details
• confirmation screen
• execute transaction
• show confirmation

Step 1, 3 and 4 are all perfect. Step 2 is missing.

To be implemented:

• confirmation screen showing the address, amount & memo
• include putting in the password here (and remove from the other screen)
• include button to approve

Added a TX verification step, I also moved the password field to step 2 (this seems logical to me) ​
