Code review comment for lp:~jamesh/account-polld/account-refresh

I was able to confirm the problem detecting new accounts, and believe I've fixed that in this branch.

It looks like the enabled-event isn't reliably sent out unless the account manager is limited to a single service type. So I've added an account-polld.service-type file along with services for Facebook and Twitter (as discussed during the call on Tuesday). The AccountWatcher now watches for all account services matching "account-polld", so gets notified of the three services we're interested in. This seems to do the trick and simplifies things a bit.

I've also disabled the debug spew from account-watcher.c, while still allowing it to be turned back on if I need to track down some logic bugs.
