Enable Changelly on Solana including in-chain and cross-chain swaps of both tokens and native SOL.
Also fix a bug introduced by me in the initial Solana release where if Changelly returns a value with too many numbers beyond the decimal point (more than the tokens decimals) then the base amount will be calculated incorrectly.
Also set priority fees for Changelly Solana transactions because otherwise they weren't being mined sometimes.

Also some minor code cleanup.
