Fix Phantom changes #11
Description
If the watcher has indexed the Files of a Hotfolder, the indexing were updated each second.
This is very expensive und error-prone.
For example:
Imagen the files are indexed and your watch interval is 1 seconnd.
You don't saw any file creation, maipulation or deletion of files where are created (maybe modified) and deleted within the watch interval, because there are now diffrence between the first indexing and the second indexing.
I call this Phantom Change, because there are a change in the folder, but this change are so fast that there are can not be tracked.
