* server/EntityFactory.cpp: Implement updating default attributes and other metadata when types are modified from the client. * server/ScriptFactory.cpp: Handle errors that occur when reloading modules. Store the new module correctly. * tools/AdminClient.cpp, tools/AdminClient.h: Change behavoir of cyaddrules so it updates types that have already been installed. Requires adding a set op types that have already been uploaded or updated, to ensure that types in a base ruleset don't override the one already in the server.
