[ANN] Lua 5.3 source code available for browsing

[Luiz Henrique de Figueiredo <lhf@...>]

The source code for Lua 5.3.0 is available for browsing at
	http://www.lua.org/source/5.3/

This was generated using the same tools as before and so there are
some errors or surprises, as reported in this lua-l thread:
	http://lua-users.org/lists/lua-l/2014-03/msg00302.html

We're still working on how to get better output.
