Add a transaction creation form so that a tx with any parameters can be created

[danjm]

It would be good if our test dapp had a form, with fields for each tx parameter, that could be filled in with any arbitrary values.

This should include the ability to set the transaction type (only to 0x0 or 0x2 for now). Appropriate gas fields should be shown for the appropriate type.

[danjm]

Add a new section at the bottom of the test dapp.

The section can be titled "Send form"

This section should contain the following labelled inputs:

• From
• To
• Amount
• Max Fee (only if type is 2)
• Max Priority Fee (only if type is 2)
• Gas Price (only if type is 0)
• type
• Data

They should all be string inputs.

The "From" field should be auto-filled with the current account.

There should be a button for submitting the form. Clicking the button should result in creating a transaction. You can follow the code for the send transaction buttons in the test dapp for direction on how to do that.

Should this be closed as #132 was merged?

@bschorchit I think it should.
