Merge pull request #105 from norv/quick_refactor

Quick refactor
I'll merge this PR, to note though: other queries related to Spiders are to be pulled out of the admin controller, refactored in specialized functions in .subs file(s). This PR was a quick refactoring of existing (and inappropriately placed) utility functions.
