[core] Adding toggle for CORS, GZIP in admin/cms configuration (#30)

This PR enables admins to disable/enable CORS and GZIP from within the admin CMS configuration page. Both are enabled by default.

Note: currently, the GZIP implementation is 100% on the fly, for every qualifying API endpoint request. This could add significant CPU usage, but dramatically decreases bandwidth. Will be considering other better implementations, but for now YMMV.

Possible optimizations:
- pooling gzip Writers vs. creating a new one for each response
- caching gzipped responses (in memory? on disk?) 
- enforcing size threshold (only gzip content larger than N bytes)
