Demo page for transaction lifecycle

[rahulrumalla]

Create a new page in the site template that demonstrates the process of sending a transaction and asynchronously waiting for the transaction receipt to happen and then to notify the user upon confirmation.

[ ] Create a new page called 'transactions' (or reuse the index page for this)
[ ] Create a neat UI aesthetic for the demo ( nothing too crazy )
[ ] Use EIP20.js store to send tokens as the 'transaction' to demo
[ ] Capture the events transactionHash, receipt, confirmation and error to display the responses on the page
[ ] Be creative on what a developer using nuxt-box could find most useful in regards to understanding the transaction lifecycle
