birdcage: TWOTEN --> SNAPSHOT
birdcage: TWOTEN --> SNAPSHOT

Problem

Not naming our poms TWOTEN confuses a lot of our automated built stuff such as maven-tools and the snapshot CI

Solution

Set the suffix back to SNAPSHOT, as well as bump the patchlevel version to every pom because SNAPSHOT < TWOTEN lexically in pants.
