Adding changes for configuration options and cleaning up code
Fixes #3 - Minor tweaks to the updates from ctoestreich.
Update to 0.7
Fixes #4 by properly handling non-Node (Rhino) compilation.
Another attempt to fix issue #4; bump version to 0.8.1
Fixing issue 4.  General code cleanup.  Defaulting purgeJS to false and adding regex to match only *.js files as it has bitten me in the butt more than once deleting *.coffee content and other files in js dirs.
Merge branch 'master' into issue4
