#701 Services plugin should retry identification if it fails

[nanotube]

Just filing a bug for future reference: services plugin doesn't retry identification if it fails with no response. it probably should. here's a snippet of my messages.log, when my bot was kicked off freenode due to some transient network outage and failing to respond to ping:

there was never a response to the identify... and the bot remained unidentified on the network, until I came by and took manual action. maybe services should retry at interval, when there's no response to identify?
