Model not triggering regeneration if placed outside template dir

[aratare-jp]

Symptoms

When changing XML model used for generation, this will not trigger regeneration.

Complication

Apparently when watching a file, not directory, on Windows, it will throw an exception:

java.nio.file.NotDirectoryException: ...\library.xml"
sun.nio.fs.WindowsWatchService$Poller.implRegister  WindowsWatchService.java: 378
         sun.nio.fs.AbstractPoller.processRequests       AbstractPoller.java: 260
         sun.nio.fs.WindowsWatchService$Poller.run  WindowsWatchService.java: 595
                              java.lang.Thread.run               Thread.java: 748

So this feature will be disabled for Windows, i.e. model changes will not trigger a regeneration. Until a proper fix is found, this is the best approach I feel.
