Add FUSD to Kitty Items

[psiemens]

Is your feature request related to a problem? Please describe.

Developers want to start using FUSD in their applications, but lack a concrete example demonstrating how to do so.

Describe the solution you'd like

Ideally Kitty Items can be updated with the following:

• Merge in generic storefront contract, which can support multiple fungible tokens out of the box (unlike KittyItemsMarket, which is hard-coded to Kibble) (issue: #9)
• We would keep the Kibble contract and minting functionality in the API
• When building the frontend, developers can use a flag to build for FUSD or Kibble
• The built UI will change based on the token option selected
• FUSD is highlighted as the default, but developers can opt to run the Kibble version if they are interested in creating their own fungible token.

FUSD Contract

You should use this version of the contract in Kitty Items: https://github.com/onflow/wallet-api/blob/main/cadence/contracts/FUSD.cdc

Here is an example of how to add FUSD to flow.json: https://github.com/onflow/wallet-api/blob/main/flow.json#L23-L28

FUSD Minting

When running the app in dev (emulator) mode, the developer can mint tokens through the UI.

When running the app in tesnet mode, the developer is directed to the Testnet Faucet (or Blocto Swap) to acquire FUSD.
