Auto Increment Build Number in iOS

incr_build_num.sh

#
# Set the build number to the current git commit count.
# If we're using the Dev scheme, then we'll suffix the build
# number with the current branch name, to make collisions
# far less likely across feature branches.
# Based on: http://w3facility.info/question/how-do-i-force-xcode-to-rebuild-the-info-plist-file-in-my-project-every-time-i-build-the-project/
