Display minimum tradeable token quantity and disable swap button if too small
Unable to swap USDC for KIN. Users reported issues with some other pairs as well.
I created a KIN SPL account beforehand, but it still fails.

- A 'custom program error 0x66' notification is also displayed.
- The transaction doesn't show up on Solana explorer
0x66 is the zero swap error, meaning the size of the trade was probably too low. See https://github.com/project-serum/swap/blob/master/programs/swap/src/lib.rs#L723.
Did you try swapping for more?

Resolved, token quantity was the issue. Consider this a feature request, that minimum required amounts should be displayed.
Additionally, we should disable the swap button if the token quantity is too small.
