1970s Canadian Police Liveries for the Moonhawk 2.2

I accidently uploaded the old thumbnails and sirens for version 2.1. Now all the stated changes of 2.1 should be present.

The Hamilton-Wentworth skin was also changed slightly.

Changelog:

1. Reworked OPP skin to be more accurate, typographically. Minor changes on many other skins. Lettering and numbers removed from rear of Edmonton PD skin as their cars in the late-1970s were blank.

2. Fixed materials.json files and re-exported skins as BC7 DDS files, meaning they should all look much better.

3. Each car will now function as a police car in AI traffic.

4. Sirens changed to be similar to the FEDERAL PA-15A, which was used by the RCMP, SQ (I think), and other...

Update v.2.0:

Added liveries for:
Vancouver Police Department
North Bay Police Service (as per request)
Halifax Police Service
Hamilton-Wentworth Regional Police Service
