* Allow messages applications to skip the compile sources phase
By default, simple iOS sticker packs created in Xcode do not include
a compile sources phase. This change will allow messages applications
with an empty list of sources to skip that phase entirely.
* Add support for launchAutomaticallySubstyle in run schemes
This is especially important for simple iOS sticker packs that require
this run scheme setting to be set to 2 in order to run the scheme
properly.
