v5.0.0-beta.1

You can track v5 beta progress in #751

You can install the v5 beta using the next tag: npm add history@next

Improvements on v5.0.0-beta.0:

• Now using Closure Compiler which results in slightly smaller and faster builds
• New global UMD name window.HistoryLibrary does not conflict with window.History
• Adds sourcemaps

A migration guide will be available soon. For now, you can either browse around the docs on the dev branch or the tests.

Enjoy!
