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

[tintinweb]

see original: https://github.com/Consensys/vscode-solidity-auditor/issues/134

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.

Taking a look

90% fixed in PR #187. Not closing because there's 10% to go. 🙈

Closing because I realised the extra 10% need a major refactoring.
