Adding ; and newline at end to avoid breakage.

When I run this as a component in IE9 it causes some errors when the source Url comment is added. It's having a hard time seeing where the end of the line is.


SCRIPT1004: Expected ';' 
hf.js?app_name=tree, line 281 character 1

Adding a semi-colon at the end solves it.

The issue happens when the build.js file is run.
