BOUNTY: New Simple Transaction UI

[JeffWScott]

Scope:

• Add Simple Transaction UI for sending Currency (TAU) and Token Transactions.
• Add the ability to select an "Advanced" Transaction option which will display the current UI
• Add a better success/failure message
• Update/Create test cases to reflect the new UI

Description

The current UI is too confusing for new users. We need a more simple UI.

The new transaction UI should have ONLY the following UI items

• What is being sent (TAU, Token Name, etc)
• Logo of thing being sent
• Dropdown box for "From" which is a list of all the user's wallet accounts
• Input Box for Receiver Address
  • This should have a "My Wallet Accounts" checkbox or switch which, when activated replaces the "Receiver" input box with a dropdown box of the user's Accounts (excluding the one selected in "From". Any updates to the From account should repopulate the "Receiver" box appropriately
• Input Box for amount to send
• Next and Cancel buttons (like current)

Creating the transaction

To send currency or tokens the transaction specifics are as follows:

Taken from CoinLamdenContract.svelte

  dispatch('contractDetails', {
      sender: selectedWallet,
      txInfo: {
          senderVk: selectedWallet.vk,
          stampLimit,
          'contractName': contractNameField.value, 
          methodName, 
          'kwargs': formatKwargs(kwargs)
      }
  })

That info is populated currently by the advanced UI.

for the new UI use these values

• senderVk VK of the account selected in the "FROM" dropdown
• stampLimit set to 50. If the user doesn't have (stampRatio * 50) amount of TAU in their account tell them they need (stampRatio * 50) TAU to make this transaction. If sending TAU you'll need to remove this from the amount they are sending to make sure they have enough left in the account to pay the TX cost.
• contractName taken from what they are sending the TAU contract is called "currency" and the token contract names can be found in the token storage.
• methodName hardcode to transfer
• kwargs "keyword arguments" these are the arguments for the transaction. The transfer method which we are calling takes two arguments, TO and AMOUNT. Populate these from what the user inputs in the UI

Send the transaction with the normal send transaction flow that the advanced UI uses.

Success/Failure Message

Add a TAU HQ link (testnet.lamden.io for testnet) to the transaction hash on the success/failure popup.
