New features and improvements
* Added support for LuaRocks 3.0.0 - 3.0.2. `latest` and `^` aliases still
point to `2.4.4`.
* `--show` can now be used when installing programs; all programs present
in the given location are listed after installation is complete.
Fixes
* `package.path` for Lua 5.3+ built with hererocks now includes `./?/init.lua`,
just as with standard Lua.
