Ignoring build generated assets, object files and library configs
Split up gtest.xcodeproj in gtest.xcodeproj-ios and gtest.xcodeproj-mac to save different build configurations for each platform
Structured, cleaned and completed the .gitignore systematically
Replace nested gtest.xcodeproj with gtest-ios.xcodeproj for the proj.ios xcodeproj file
Added gtest-mac.xcodeproj to LevireTemplate.xcodeproj for the mac
Added test runner and test sample to the mac xcode project
Added "Tests" target to the mac xcode project
Fixed missing libgtest.a, which was removed due to the renaming of gtest.xcodeproj to gtest-ios.xcodeproj
Added missing call to TestRunnerScene::testIt, which got lost during refactoring and results in all test not being run
