Hotfix v0.28.15

Hi folks! One more little hotfix with fixes for a few remaining edge cases from the Slimline Update earlier this week.

Fixes:

• Fixed a bug in the redo of destroying network cables/fibers.

• Fixed box-select to be able to select network cables/fibers.

• Fixed network cables and fibers, and also bridges and walls and a few other elements to not be drawn when we know they're outside the view frustum. This is probably only a tiny performance improvement, but every little bit helps, right?

• Fixed the new slider widgets to work better in the dungeon paint fill options UI.

• Fixed a potential crash during game shutdown (post-autosave) if you quit immediately after using a flight point placement tool, or if the most recent tooltip displayed had been showing a flight point model.

• Fixed a potential crash during game shutdown (post-autosave) if you had changed the filter options on the Subscribers list in the Game Overview report.

It's been a busy week of fixes! Huge thanks to everyone who's sent us feedback and bug reports!
