Implementation

This could be done by having something like a lang or languages folder within a contribution (library/mode/example/tool) which contains files like properties.de, properties.fr, properties.es and so on. Each of these files would need to contain only a sub-set of fields present in the library.properties file (for example). These fields would primarily include name, url (in case the author has his/her webpage available in several languages), sentence and paragraph. No changes will need to be made to the contributions.txt, and this feature won't break a Contribution Manager that does not support internationalization.

I shall get cracking on this soon (once some of the more pressing bugs in the Contributions Manager are resolved), although I'm not quite sure about its priority.
