[proposal] introduce global configuration

[DRiFTy17]

Proposal

It's common that components will need to be used consistently across a product many times and instead of having to configure
component properties/functionality multiple times, it would be better to configure this once via flags before the library loads to
ensure that they operate with different default values and interactions across the lifetime of the application.

We could potentially implement this as just a global configuration store on window with keys for specific components that required and discover those default at runtime.

Affected components

All.

Benefits

• Allow for developers to set common defaults once instead of having to set them everywhere they are used.
• Globally turn on/off features such as ripples (any JavaScript-based functionality basically).

Caveats

• I'm not necessarily a fan of utilizing window for this but may be our only good option
