Andrew Nacin db981a3b27 Switch to .min for compressed JS and CSS files.
* This moves our "development" versions from .dev.js to .js (same for css).
 * The compressed version then moves from .js to .min.js (same for css).

By switching to the standard .min convention, it sets expectations for developers,
and works nicely with existing tools such as ack.

fixes #21633.
