[compiz] N_ macro

[Mike Dransfield]

I have just updated the place plugin to use integers
rather than strings with restrictions (as per the other
plugins).

The only thing which is now using the N_ macro is
windowTypeString which I think can be removed.
I think some plugins may still be using this so I have
not removed it just yet.

Once this is gone it will be possible to remove the N_
macro as well, is this OK?
