Patch _get_all() to handle group svc_id values

This just changes this so it does not try to return back last_options
from the configuration dict.
Enable insertion of group-powered TTS tags

Patches the templater dialog to understand groups and how to insert
those tags.
Skip preset matcher search if using group

This skips the next() block search to find a matching preset if we are
on one of the group selections.
Add support for recording via a group

This enables the user to get random or in-order voices easily.
Disable throttling support temporarily

This is going to need to be done per-service now, but the current code
does not support that.
Patch browser generator for Groups support

Guards the services options lookup and adjusts the router call.
Begin passing svc_id with miss callback

This is intended for use by the generator to keep track of throttling
per service.
Add per-service throttling support

This is done by keeping a lookup dict instead of just a flat number of
download calls. Once any service has hit the limit, all mass generation
is temporarily throttled.
Merge branch 'add/groups-6-30-31-32.browser-gen'

Adds mass generation support with groups.
