T.P.Lua: expose more useful internals (API change)

Newly exported from Text.Pandoc.Lua:

- `runFilterFile` to run a Lua filter from file;
- data type `Global` and its constructors; and
- `setGlobals` to add globals to a Lua environment.

This module also contains `Pushable` and `Peekable` instances required
to get pandoc's data types to and from Lua. Low-level Lua operation
remain hidden in Text.Pandoc.Lua.
