Problem on saving the progress of a document

[Nikos]

On version 0.13.10 when you save the progress of a document sometimes everything its ok(the red icon turns blue and the doc is been saved),but the most of the times after saving an alert box appears saying:
"The document "..." has ben modified.Do you want to reload it?etc...".
There is no need for alert box in this situation,but even if this is the policy,there is a problem too,as you have to push the button "reload" at least twice so you could continue your task.

That's a bug.
It should be absent in the complete rewrite of notepadqq (git).

The problem seems to be the QFileSystemWatcher, which somehow doesn't get disabled at the right time.

Apparently events are getting queued up in the background during the save process and firing upon the file watcher becoming re-enabled. There are a few ways to handle this, such as:
- Still emit signal from internFileChanged, but throw away when we reach mainWindow's fileChanged function.
- Remove the path being watched upon the file watcher becoming disabled and vice versa.
- Disconnect event/signal handles until saving is completed entirely.

I'm not 100% sure which one we would prefer here, but it is likely that disconnecting the signal all together might be the best approach, but I've been wrong before.

The other two options are just as effective, in either case.
