Using Context instead of Rules (#68)

* Committing to test on new environment * Can execute pre-configured reactions through Context UI * Exporting actions * Adding contexts * Renaming * Using switch in hook implementations * Ready to test without rules and just context * Trimming down hooks and removing dsm() calls * Fixes after testing large batch operations * Functional tests and more testing * Coding standards * Removing duplicate * Config export * Removing media bundle condition for now. * Tightened conditions. Fixed context caching bug. * Ignoring schema exceptions and disabling module provided contexts in functional tests * Oh that's hilarious * Responding to @whikoj's feedback * s/deindex/delete * Coding standards
