Share the schemes accross the repository. Add a new scheme for the PlayynomicsSDKTests, although this is redundant this allows us to run xctool for automated tests and for using CI with travis. This might be resolved soon though, with this change request: https://github.com/facebook/xctool/issues/187
Adding config file travis CI. Can't merge with master until xctool v 0.1.13 is available in homebrew.
