Generating the graph with type casting address(...) as a function.

[andreitoma8]

When generating a call graph, the extensions sees typecasting like address(this) or address(some contract/interface) as a function and this is not only incorrect, but also visually clutters the chart. See example:

I think the fix should be pretty easy on this, just adding logic to ignore a function if it's name is address since that's impossible anyway in Solidity because the term is reserved for the type.
