Story (A paragraph or two describing what happens)

Admin wants to be able to alter messages easier

i.e. instead of giant i18n/messages that you have to alter have a base messages.xml (with all 10,000 keys) and then a messages-custom.xml (with 200 keys that overrides). Also, to change the site name from "DSpace" to "Scholar Archive", you don't have to alter 200 keys.
