Major refactoring

[avoidwork]

• Optimized closure to not rely on abaaso namespace where possible
• Created state to abstract application state more efficiently
• Curried array.cast(), array.keys(), utility.property() & utility.iterate()
• Upgraded build dependency to gruntjs 0.4.0
• Generating a source map (not that useful due to closure it seems)
• Fixing client.version by allowing floats and parsing Chrome's & Opera's version properly
