1.0.0: Drop bower, component, the browser version and make the code and tests sane

[lydell]

This will be breaking changes.

• Drop bower, component and the browser version.
• The async functions should probably use promises.
• The sync functions could be removed?
• Make the code and tests sane.

The above checklist has mostly been cleared by the awesome @andy128k!

I’ve got some more tweaks I’d like to make, but the bulk work is done.
