The "module-help" modulefile command has been introduced in Environment Modules 5.6 to provide a way to define help messages simpler than the traditional ModulesHelp procedure, like achieved on Lua modulefiles with the "help()" function.
This commit adds "module-help" support for Tcl modulefiles and make it map to the "help()" Lua function when translated by tcl2lua.tcl.
