Consolidate config into single external resource

[devunwired]

Currently, event-specific config data spans the following locations:

• js/config.js
• js/factories.js
• .firebaserc

Consolidate everything specific to a single event into one external source that is not committed to the repository.

Side Note: We should probably remove event logo images as well.

Agreed.

My initial idea for this, and why the data is structured under an events/event_name level is that you could host multiple events (like all 360 events) from a single instance. Ideally, to support that, the logos would be part of the config, served from cloud storage, and configurable from the admin panel.
