Update to Hotfix v3.0.19a

Update to 3.0.19

Fixed rotary dumpers even harder this time

Fixed a bug with rotary dumpers not aligning properly in multiplayer.

Added tp3_loada_packetsize, a client console variable for users to limit the rate at which the server sends Trakpak3 map data to client. This should fix reliable channel overflow errors on joining Trakpak3 maps, but can be adjusted lower if necessary.

Fixed some bugs including Dedicated Servers crashing on map startup for certain maps.

Bug fixes relating to map cleanups, and added short bridge transition models.

Added defect detector distance and volume options for tp3_cabsignal_box. Added rotary dumpers!

AAR Plates, Banked Curves, and SigEdit improvements

Lua fix for some exotic hook issues on some servers, improved blacklist system to reduce even more lag.
