few problems with react 15.0.2
I just updated react to 15.0.2 and react-color to 2.1.0

now I face some problems

First, I use `color.rgb` to get color I choose but picker seem cannot get the value correctly (or other problems?!) cause it couldn't update properly, alpha cannot slide and circle pointer cannot move
but I still can get the color value 

same problem occurred by using `color.hsl` too

Second, HEX field show double # like `##FFFFFF`, it isn't correct, is it ?
official site also got this problem 

Third, in chrome picker, the button which control showing HEX, RGBA, HSL field, got some wired problems
hover cause it flash?! and nothing happen when clicked it ... (browser problem..?!!) 
Im testing on Safari 9.1

Fourth, same problem #114, I fixed it by modify all `Absolute: 0 0 0 0` to `Absolute: 0px 0px 0px 0px`
