Add XCTest logger backend to QtTestLib

Will be active when running test apps through Xcode's 'test' action,
and reports QtTestLib test objects and functions to Xcode as XCTest
cases.

This allows running tests on both iOS Simulator and iOS devices from
the command line, through xcodebuild, without relying on any 3rd party
tools. It also integrates Qt test failures and passes into the Xcode
IDE, which may be useful for closer investigation of test failures.

The feature is limited to Xcode 6.x.
