qr.js 1.0.2

Today I made a quick 1.0.2 release for qr.js which contains renamed methods within the API which I feel will make it more simple and understandable to use.

I strongly recommend using QRCode.image and QRCode.canvas from now on as their old method names will probably be completely removed in a future release (not sure when though).

Changes

• Deprecated generateCanvas and generateImage and replaced with canvas and image respectively
