[NEW] Centralized external resources references

[NEW] End of the Chaos: Centralized external resources references

`+` updated to latest versions of jQuery 1.11.1, Chosen 1.1.0, jQ Validate 1.12.0
Nor this: 'general.cdn_use_https'

Also If I remember well with KO you can detect the protocol so if its using https then the CDN should be https forced.
