Add hotspot description to pulldown

[Crystal-Shard]

Describe the problem
The hotspot pulldown would be much more useful if it shows the description of the hotspot, instead of showing in parentheses that it's a hotspot.

Suggested change
Currently it says "hHotspot6 (Hotspot; ID 6)", it would be nice to change to e.g. "hHotspot6 (door; ID 6)". I'm mentioning this because many games don't change the name of each hotspot but they do change the description so that mouseover text works. This applies to the pulldown in the properties panel, too.
