Fix 500 on customer revision when revision_history table is missing

Browse source 
Deployed databases can persist without the revision_history table,
causing /play/<token>/revise to crash with sqlite3.OperationalError.

- log_revision() now creates the table on the fly if it is missing.
- app.py runs init_db() at import time (safe CREATE TABLE IF NOT EXISTS)
  so new deployments auto-create missing tables on startup.

Bump patch version 0.4.0 -> 0.4.1.
