inject: Major refactoring

This addresses one major issue and multiple minor ones:
Major:
Inject's debugger is not attached to the process before
injecting DLL files. This misses out on OutputDebugString
calls by anything logging in the DllMain functions of the hook
dlls.

Minor:
- Fix coloring of log entries
- Add ASCII header to easily determine start
- Fix file logging, log _everything_ to a single log file
- Enhance inject's debugger: log further debug events to incrase
visibility on issues, proper exception handling for inject
- Re-iterated code structure of inject
