Maven: update plugins
Remove spurious comments
rename parameter to avoid confusion
Remove unused getter methods (which only make code inspection harder than necessary)
PagingManager and PagingStoreFactory do not use the PostOffice reference
Remove PostOffice.getPagingManager() as everywhere using it had access to server.getPagingManager()
Remove PagingStoreFactory.setStorageManager(...)
Remove hard coded version. Use "Version" class to set it.
Merge pull request #763 from FranciscoBorges/master

Mostly dead code deletion. Also fixed hard-coded version String
