Subject: Add --input-dir and --output-dir as options (#119)

All filese from --input-dir will be processed as templates and stored
with the same directory hierachy in --ouput-dir

- Use both options when a whole directory hierarchy needs to be processed.
- Extracted file processing logic in an extra process.go
- --output-dir is optional and default to "."
- --output-dir is created automatically if not existing

Fixes #117
