Setup for bower registration

I was able to successfully register as log4js-gabe and bower install it into my project.  I've updated this commit so it can be registered as log4js.  When this commit is merged you will need to create and push a '1.0.0' tag.  Then run:
$> bower register log4js https://github.com/stritti/log4js

Or I can do it once the tag is created.

Thanks for the library.
