Lua source code history now available

[Daurnimator <quae@...>]

At the workshop this year I spoke about my efforts to convert the
historical source code of lua into git form.
I finally put the last pieces together (sorry! I promised it by
october...) and have now pushed the results to github.

It's split into 4 repositories:

  - Main source: https://github.com/lua/lua
  - Tests: https://github.com/lua/tests
  - luac: https://github.com/lua/luac
  - manual: https://github.com/lua/manual
