[ANN] Pluto 2.0 released

["Ben Sunshine-Hill" <sneftel@...>]

After a 2-year, uh, maturation period, Pluto 2.0 final has been
released. A tool for serializing arbitrarily compex Lua data, it is
useful for savegame features as well as simulation rollback points. It
also has miscellaneous uses wherever you want to package up Lua data
and send it to a different lua_State. The 2.0 release contains
numerous bugfixes, but still weighs in at a svelte 2 public functions.

As always, bug reports, feature requests, and usage reports are
greatly appreciated.
