Cannot set if historyContentView.backgroundColor

Hi!
First of all, I would like to say that this is one of the greatest new functionality I have seen in a long time, It perfectly fits in my app!

There is just one little tiny detail on iOS 9.2 setting up background color gets overriten in SAHistoryNavigationViewController.swift on line 49. I haven't tested this on any other version of iOS, but I am pretty sure that it won't work also.

So I have made a really tiny change, basically just check if backgroundColor is already set, if so It won't get ser on grayColor.

Tested and It works now.
