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

+Builds sources in the current directory, but unlike "build",
+it does not fetch sources, etc., assuming everything is 
+available in the current directory. If no argument is given,
+it looks for a rockspec in the current directory and in "rockspec/"
+and "rockspecs/" subdirectories, picking the rockspec with newest version
+or without version name. If rockspecs for different rocks are found
+or there are several rockspecs without version, you must specify which to use,
+through the command-line.
+
+This command is useful as a tool for debugging rockspecs. 
+To install rocks, you'll normally want to use the "install" and
+"build" commands. See the help on those for details.
+
+--pack-binary-rock  Do not install rock. Instead, produce a .rock file
+                    with the contents of compilation in the current
+                    directory.
+
+--keep              Do not remove previously installed versions of the
+                    rock after installing a new one. This behavior can
+                    be made permanent by setting keep_other_versions=true
+                    in the configuration file.
+
+--branch=<name>     Override the `source.branch` field in the loaded
+                    rockspec. Allows to specify a different branch to 
+                    fetch. Particularly for SCM rocks.
