Refactor luagenerator

- cleaned up the generation
- created special class to handle the serialization
- improved string escaping: Replace OS Path separator with normal slash and allow the usage of a single quote in unit names by changing the delimiter to double quote instead (1797)
- adjusted unit_name generation to prevent scripting errors with unescaped characters
