nmhive.py: Add --debug option

I'd removed a hardcoded 'app.debug = True' in bdbfab1f (nmhive.py: Use
notmuch behind GET /tags, 2014-09-21) because it conflicted with a
global, read/write lock.  However, in a98096f1 (nmhive.py: Use
per-request database connections, 2014-09-21) I dropped the global
lock, so enabling debuging is feasible again.
