increase per_page value to 200 for github.getTags api call

this is not a true fix, there is a problem w/ the github npm module
in that it does not return latest tags first,
the fix will forstall the issue for a bit
- will file an issue report w/ github npm repo to address ordering of tags
removed console.log calls
Merge branch 'master' of https://github.com/ajsnapshots/libgrabber
add export for util.install_copy
