Enhancements

Fix a bug that Clash may interpret pure number password as float64 type (Issue [#58](https://github.com/tindy2013/subconverter/issues/58)).
Fix support for parsing some non-standard Clash configurations.
Add generator-only mode to save configurations to files or upload to Gists.
Optimize codes.
Fix typo.
