Reload settings after the file is changed

[dero]

Right now users need to close and reopen the app. This sucks.

• Ideally the app would pick up the settings.ini file change. Probably using FindFirstChangeNotificationA.
• Alternatively there could be a refresh button in the UI in case the former approach would not work for any reason.

Note: Make sure it works for profile settings, i.e. settings.<profile_name>.ini files as well.
