Sync UniswapV2SwapRenamed with UniswapV2Swap

[mariaKt]

This PR updates UniswapV2SwapRenamed.sol to be in sync with UniswapV2Swap.sol, while applying the same changes as #28, namely:

• change names starting with a capital letter. We simply change it to a lower case letter (contracts, interfaces), or append a descriptive prefix (constants, events).
• removing _ from names. We change shake case to camel case, replace the _ with a prefix if it is a the start of a name (fid for function identifiers, vid for variable identifiers), or entirely remove the _ if it is within all capital letters.
• make sure that mapping key types are named.

Accordingly, we change the corresponding reference and transactions files and update the rule for the summary of the initial configuration.
