Migrate from detours to mhook-2.3

What we lose: 
 - Transactional hooking (not really needed, and might we need it we can implement something with similar end-behavior at mpc-hc level)

What we gain:
 - Src code with gpl-compatible MIT license

There is also an option of [easyhook](https://easyhook.codeplex.com/) if there will be problems with mhook.
