*	[BREAKING] Use client-side translations instead of intllib; add zh_CN ↵	ywang	2020-07-19
| | | | | | | |	translations * Client-side translations is used instead of intllib. [Breaks MT4 compat] * Existing locale files have been moved to advtrains/locale and named with the format advtrains.[lang].tr * Add zh_CN locale. (requires a font that supports CJK text)
*	Use a standard wagon inventory formspec	Blockhead	2020-03-18
| | | | | | | | | | | | | |	This new formspec also allows access to the wagon properties. Once whitelisted in the wagon properties, other players can access its inventory. Note on 'useless use' of OO: I tried passing just the wagon ID and avoiding using the `self` object in order to bypass the need to look up the lua entitie out of the list, but it ended up retrieving nil data. The best way to solve this overhead might be to wait for some kind of better way upstream in minetest's lua API to get entities, or to keep a central record of entities. Either way, the solution is outside the scope of this commit.
