Auto-refresh of tileset files only works for 1 refresh about tiled

As of change bd17698 you can also press Ctrl+T to force-reload all tilesets of the current map.

This issue came up on irc again:

chillyguess: Oh yep, we figured out a workaround
chillyguess: create a batch file, and use xcopy to 'move' the files to another folder and get Tiled to use that folder instead for tilesets

The cause of the issue is in FileSystemWatcher::onFileChanged() (in filesystemwatcher.cpp). When saving from Photoshop, mWatcher->files().contains(path) returns false, but QFile::exists(path) returns false also, so the file is never readded to the watcher.

Not sure what would be a proper way to fix it. One way might be to also watch the directory where the file is/was, and add the file back to the watcher if/when it reappears in the directory.

Thanks for investigating this @fo-fo! At least this gives us a clue about why it is breaking with Photoshop and we can consider ways to fix it, but indeed it seems we have to start tracking the directories also.
