Add debug package to log insetad of print directly to console

[vukanac]

Use debug package for log instead of printing to console log.
This will prevent non-wanted printing a lot of log lines.
If a user wants to see what partials are loaded, just set debug target:

$ DEBUG=* node index.js

Change:

• Add debug package
• Change console.log() with debug()
• Remove some extra spaces from line endings.
