Defer sticker reads via crl::on_main chain for faster first paint

Browse Source 
Instead of reading all sticker sets synchronously in crl::on_main,
chain each read step via crl::on_main so that paint events can be
processed between heavy file reads. This moves first paint from
~2807ms to ~1294ms by allowing the UI to render before sticker
loading completes.
