make a mechanism for monitoring the hashes of remote files

[marpaia]

I can see a big impediment to a successful chef run being all of the checksums mismatching because apps got updated. write a script that i can cron that will download files to /tmp or chef cache every so often and let me know that hashes have changed (and perhaps automatically update them if i say it's ok).

[marpaia@-rue] chef-osx (master):egrep -ir -A1 "^default.*source.*http" ./ | grep -v "\-\-" | awk {'print $3'} | sed 'N;s/\n/ /' | sed 's/"/ /g' | sed 's/   / /g'
