Transfer test ARC token to another user

[sponnet]

As a driver I want to be able to send ARC to a rider to immediately pay for a ride. This is the equivalent of paying cash for a ride , but registering the transaction on the blockchain so that the driver and rider reputation can be built up.

Works by displaying a shortcode to the driver containing a transaction batch. ex:

• transfer 20USD worth of tokens to rider's wallet
• rider creating allowance on his wallet to smart contract
• rider sending 20USD worth of tokens to driver
• displaying confirmation screen for both driver and rider.
