Slightly WIPish
Revert "NOOP: Ignore project targets."

This reverts commit 18d71f209dfa711bda8de69bfc5a491b8ff3271f.

Each project already has its own .gitignore
some integration test fixes
Allow implementation-specific system columns to be created.

Those are "anything that begin with `:@' and is otherwise a valid column
name".

Needed for old-backend integration.  This is temporary.
re-add the endpoint to get the data version from d-c
Add boolean and floatingtimestamp to JsonColumnRep.
