Logging rework

[isanae]

This is not as bad as it looks.

A lot of the modifications are actually moving all the logging stuff I did a while ago for modules, AVs, etc. from util.cpp/h to a bunch of new env*.cpp/h files. You can collapse these files.

• I changed all qDebug(), qInfo(), qWarning() and qCritical() to the new logging functions. This is the bulk of the changes.

• I renamed logbuffer.cpp/h to loglist.cpp/h, because it also handles the widget. I moved the widget to a docked window, changed the timestamp to include seconds and milliseconds, and added options to the context menu to clear the log and change the log level.

• Qt is buggy when saving and restoring dock positions. I added a class DockFixer in mainwindow.cpp to fix the problems, all the gory details are in it.

• I added some logging on startup:

  • All configured executables;
  • Basic checks for missing files that are typically eaten by AVs in checkMissingFiles();
  • A specific check for Nahimic drivers that are known to cause issues in checkNahimic();
  • A list of all displays, graphics adapters and DPI settings.

• I removed a few logs that were noisy and unhelpful, such as the "network interface seems up". I also deleted a few commented out code blocks.

• OrganizerCore used to have the Settings object as a member variable, initialized by a QSettings passed in the constructor in runApplication(). Since logging has to be initialized as soon as possible, and I need the log level from the settings, I moved the Settings object to runApplication() itself. OrganizerCore only has a reference to it now. It doesn't change much, just that Settings is created earlier.

• It used to be that logbuffer.cpp would register a callback to Qt's log to add entries to the list. This is now reversed: main.cpp registers the callback in qtLogCallback(), which forwards to the new log functions. The log list now has a callback to the new log instead.

• I removed getCurrentErrorStringA() and getCurrentErrorStringW() from errorreport.cpp/h because they were redundant and used only in a few places. Now everything uses formatSystemMessage().
