Reland #1: mac: Migrate xibs to OSX 10.9.5, Xcode 5.1.1.
The original CL failed to land because some of the WebKit testers were also
building on OSX 10.6 and OSX 10.8. Those tests have been updated to no longer
build.
> To generate this change, I ran the command "find . -name *\.xib | grep -v
> third_party | xargs open". For each file, I changed "Opens in" to "Xcode 5.1"
> and "Builds for" to "OS X 10.6 and Later".
>
> I ran this process twice and diffed the results to ensure that I didn't
> accidentally change any of the xibs in an unintended fashion.
