hotspot: Add backend changes for non-intro hotspots.

This commit introduces non-intro hotspots.
They are a bit different than intro hotspots in the
following ways:

* All the non-intro hotspots are sent at once instead of
sending them one by one like intro hotspots.

* They only activate when a specific event occurs,
unlike intro hotspot where they activate after the
previous hotspot is read.
