Updates for CAG8 v1.10

In preparation for the release of my Orbx Pender Harbour CAG8 v1.10 I’ve updated the ferry system traffic file to fix an issue around Stillwater Bay which is now part of the Pender scenery. Please see the top of this page: https://larobinson22.wordpress.com/interim-updates/

There are a couple of other minor fixes too. The PR at the Powell River ferry terminal and the Powell River Mill has been redone with a water mask to improve the shoreline. At some point I may add seasons to the PR but matching them to FTX PNW is a time consuming process. The flattens in these areas leave something to be desired but the fix will have to wait.
