about SCREEN_WIDTH in UIDevice+BFKit.swift

[jiongge]

UIScreen.mainScreen().bounds.size is same regardless of the direction of mobile phone before iOS_7_1 ,but it's changed after iOS_7_1

for example:
////////////////////////
func getFixedScreenSize()->CGSize{
let screenSize=UIScreen.mainScreen().bounds.size
if((NSFoundationVersionNumber <= NSFoundationVersionNumber_iOS_7_1)&&UIInterfaceOrientationIsLandscape(UIApplication.sharedApplication().statusBarOrientation)){
return CGSizeMake(screenSize.height, screenSize.width)
}
return screenSize
}

Thanks, I've made some tests and seem that your solution works!
I'll implement it in the next version.
