Summary of Changes

This contains 2 new main new additions to the epic branch for the SKALE transfer bridge

1. A faucet that distrubutes a small amount of skETH once weekly - enough to cover several transactions.
2. A check upon trying to exit from the SKALE chain that a user has enough rinkeby ETH in the community pool for the exit to succeed.

Testing Considerations

Faucet

1. Open up the bridge and switch to the SKALE side of the bridge - there should be a banner allowing you to request skETH - clicking it and waiting should credit your wallet with a small amount of skETH and the banner should not appear again unless you transfer the skETH to another wallet address - if you do this then a subsequent request for more skETH within a week should fail.

Community Pool ETH balance check

1. Try to transfer skMINDS into MINDS while the Community Pool (fund exits) balance is 0.
