londiste: inform about no tables passed on cmd line (thus nothing to do)
python: text fixes
scripts/data_maintainer.py: added suffix "3" to service name
londiste: initial implementation of shard-ed Dispatch handler
skytools.scripting: more safety in run_func_safely()

Scenario resolved:
startup() fails and some variables are never initialised.  those are used in overridden send_stats() which is called from generic exception handler in run_func_safely().  thus a new exception is raised that would obscure the original exception raised in startup().
londiste: changed handler argument 'key' to 'hash_key'
londiste: moved hash_key logic from dispatch to part handler
londiste add-table: --skip-non-existing ignores tables not on provider
Merge branch 'feature/dispatch_handler_with_sharding' into develop
londiste.handlers: fixes
londiste.handlers.dispatch: added switch to ignore events aiming at obsolete (dropped) partitions
londiste.handlers: renamed handler 'part' to 'shard'

It was getting more and more confusing, especially since 'dispatch' handler mixed both partitioning types (table and database) in one class.
londiste.playback: support multiple -v options for workers
londiste: resync supports --find-copy-node and --copy-node options now
querybuilder: show list of missing arguments on KeyError
londiste: add-table supports --find-copy-node working with --create now
londiste --wait-sync: show progress in absolute numbers

This gives more information and is less random.
news: fix date
Merge remote-tracking branch 'gamato/develop'
londiste: fix multi -v passing
