Custom Fixed ratio support

[hannut91]

Current plugin is fixed ratio to square only.
I modified to change according to parameters.
if no parameter ratio, not fixed crop..
if parameter ratio greater than 0, fixed ratio crop

hey ! I'd like this. I think its a great idea.
could you merge this ??

I think this project is not alive.
So you can get my code and use it

bug fix when custom ratio is required

I think this will be better on the iOS version
If you need to set the width and height, you can add the following two parameters if you do not need to add
widthRatio: You need the width,
heightRatio:you need height ,
