Console parity

• debug-logger input syntax matches node's console for easier adoption:
  • Added log.time() and log.timeEnd();
  • Added log.dir();
  • Added log.assert().
• By default trace, debug, log and info output to stdout while warn and error output to stderr. This is configurable;
• log() now outputs through the default/root debug instance.

A namespace per level

• Setting the color on debug instance itself to match a given level color;
• All levels have their own debug instance by default with level name added to the namespace;
• Removes INFO, WARN, ERROR, etc prefixes from log message (namespace already includes these);
• Added example on how to configure debug-logger the same way as in v0.3.1;
• .config() method now supports customizing levels.

Ensure newline upon writing to stream

• Spying on stdout/stderr to figure out if last output ended on '\n' or not;
• Performance: don't process arguments unless debug instance is enabled;
• Show object inspection inline if not too lengthy;
• Highlighting improvements.

v0.3.0

v0.3.0

• Lazy loading debug instances: only when they are used for the first time they are actually instantiated;
  • Note: this breaks the interface. log[level].logger becomes log[level].logger() and log[level].enabled becomes log[level].enabled().
• Added support for multi arguments (like console.log). Multiple arguments are concatenated using space as separator;
• Added support printf()-like formatting elements (like console.log);
• Added support for a new DEBUG_LEVEL env variable where it's possible to restrict the level of output shown. Examples: DEBUG_LEVEL = warn | *:info | myapp:2,otherapp:debug
• Some highlight changes, most importantly stack trace will be printed in the same color as the level (e.g. red for error);
• Added trace level.
