Breaking changes
* `hererocks --luajit 2.1` now installs LuaJIT 2.1.0-beta2 instead of
using v2.1 git branch. Use `hererocks --luajit v2.1` to get old behaviour.
New features and improvements
* LuaJIT versions 2.1.0-beta1 - 2.1.0-beta2 are now supported.
* Lua is now built manually (`make` is not run).
* OS X 10.4+ support for Lua 5.1.0 - 5.1.2.
* SHA256 checksums for downloaded archives are now verified (13).
* `--no-readline` flag for building Lua without readline library.
* Lua archives are now downloaded using HTTPS.
Fixes
* `luajit.h` is installed for LuaJIT (11, 12).
* `jit.*` modules work correctly for LuaJIT 2.0.1.
