Script to work in any kind of Debug configuration

If configuration's name was in another shape than "Debug" this script always failed to append branch. Updated the script to match the configuration with contains method, meaning branch will be appended even if configuration is called: "AppStore.Debug" or "AppStore-Debug".
Bootstrap update if configuration contains release

Similar to Debug, there could be a configuration named "AdHoc-Release" or similar that has some specific settings. This commit updates the script that it is treated as Release, as soon as the build configuration contains "Release", not matches directly.
