WIP: Replaced signature files with custom .hpp headers to allow address conversion at compile time

[Patrix9999]

The current behaviour with address resolution is crappy, because it relies on the runtime finding of given signature.
This pull request aims to move this problem into compile time evaluation, so that the compiler automatically replaces the given method names with address values, which is much quicker in the end on compiled plugins, however...

There are still some problems, that needs to be somehow addressed, here's the list of some of them:

• What should we do, when the exact method name exists with more than one variant? (custom overloads, different arguments/return type)
• more?
