Soup 0.4.0 (Alpha)

Breaking Changes:
-c "config" flag was replaced with -flavor flag. (Gotta have some more of those food puns)
Converted all build execution over to using build graph internally, should have no impact on normal usage.

Note: To help keep our versions under control, during active initial development we do not follow strict Semantic Versioning. Instead we allow breaking changes in Minor updates.
