KDE Connect File Sync plugin

[vineet garg]

There is QFileSystemWatcher in Qt and a FileObserver class in android which
can monitor a specified directory so that we don't need to calculate and
compare hash each time. I have never used them, but looking at the
documentation it should work fine. Plus there can be periodical packets
like in every one hour with list of files with their hashes to update any
file if needed or this can be only when the device is added to sync any
file added when the device was not reachable.

Cheers!
Vineet
