[cursey]

This PR allows you to create hooks that start disabled and allows you to explicitly enable or disable them.

Closes #72

[ThirteenAG]

I noticed that I'm having a crash on exit with current main branch code in some games, only in debug, while https://github.com/cursey/safetyhook/releases/tag/v0.4.1 works fine.

Unhandled exception at 0x65F2F130 (CoreUIComponents.dll) in Condemned.exe: 0xC0000602:  A fail fast exception occurred. Exception handlers will not be invoked and the process will be terminated immediately.
