This is an important refactor of the way documentation generation works

* Installs luarocks WITH it's executable (easy to install other rocks if necessary)
* Use Lua supplied with luarocks
* Create Utils/luadocumentor.bat, which works with RELATIVE PATH ! -> Everybody can generate the doc
* Updated launch files accordingly

Utils/luarocks/systree/share/lua/5.1/template/index/recordtypedef.lua
