map_trees deals with both string and table trees

Fixes #178
fixed command line parameters with spaces
reorganized help description
fixed whitespace
fixed issue with double quoted arguments
minor text update
Several updates:
1) will search the system path for Lua interpreter if no location is found. Only then the ancient defaults will be checked.
2) if /LUA is provided, it will only look there, and fail if not found instead of falling back to the defaults
3) if no interpreter found, it is not automatically installed. Only with explicit /L switch the included interpreter is installed

Allow the wrapper scripts to keep working even if LuaRocks is uninstalled
(or if one is building them to run in another box without LuaRocks,
for example, in cross-compiling scenarios).
