3.0.0

• Refactored source into commonjs modules.
• Tooling overhaul: browserify/watchify/uglifyjs instead of manual compilation script w/ closure compiler.
• Cleaned up directory structure. Source lives in src, zxcvbn.js lives in lib.

Backwards-incompatible changes:

• Removed zxcvbn-async-loader.js / zxcvbn-bower-loader.js, moved these into README under new performance section. Will break old bower setups.
• Removed zxcvbn_load_hook()
