Cannot Approve Token for swap

[talonZack]

User Story
As a user, I should be able to approve Uniswap to transfer a token, so that I can swap that token for another.

Current Behavior
If the allowance for Uniswap to move the input token is 0, then the action button is just disabled

Expected Behavior
If the allowance for Uniswap to move the input token is 0, the action button should show "Approve" and clicking it should propose an approval call to the user's wallet
