Distinguish var balance and this.balance

[s-tikhomirov]

In both cases, balance is highlighted as a keyword. In reality, the former is just a variable, whereas the latter is a property of an address.

Same problem with all special properties, e.g., msg.foo, block.timestamp, etc.

One thing that might help is to add alsoletter={.}, to \lstdefinelanguage. Then you can have this.balance as a keyword.
