Radare2 integration

[XVilka]

Radare2 is a binary analysis and reverse engineering framework, that has disassemblers, analyzers, emulation, debuggers, diffing engine, etc. So it might be beneficial for Veles to do some kind of integration, at the very least for analyzing the code parts, magic search and emulation-based data visualization (to be able to visualize the data structures that are accessible only in RAM, e.g. after running some piece of code).
