BUG: OMERO Windows server, admin script serve fails

[sylittlewood]

When attempting to enable a script processor on a Windows Omero Server the following error is reported on the command line:

C:\omero_dist> bin/omero script serve

UnboundLocalError: local variable 'old' referenced before assignment

This seems to start the processor now and 'some' scripts will now load but some wont

Fixed and pushed to my sprint12-server branch.

(In [1804cabf5d98c6ac4a9b454cbafc62a6cdb3a5cd/ome.git] on branch develop) Separate win and nix handling of script serve (Fix #8554)

signal.SIGALRM is not available under Windows. Since there's
no standard way to timeout the invocation of raw_input under Win32,
I've simply disabled it. Using msvcrt or similar, we may be able
to add this functionality later (though this clearly never worked
except on posix systems)
