We need to be able to do an API request that omits collections that have < 2 collections. The API doesn't support this.
The output would be similar to: http://en.m.wikipedia.beta.wmflabs.org/wiki/Special:GatherLists
== Deploy instructions
Vagrant: run `mwscript update.php --wiki=mobilewiki --quick` (or just `vagrant git-update` if you prefer things that way) then `mwscript extensions/Gather/maintenance/updateCounts.php --wiki=mobilewiki`
Beta: (to be figured out)
Production:
* before the patches go live: log in to terbium, create a local copy of `add-gl_item_count.sql`, run `mwscript sql.php --wiki=<wiki> ~/add-gl_item_count.sql`
* after the patches went live, run `mwscript extensions/Gather/maintenance/updateCounts.php --wiki=<wiki>`
This needs to be done for each wiki where Gather is enabled.
