Update for TSW Starters Guide and new Route Guides

[RudolfJan]

I updated the TSW Starters Guide for TSW2020, including Mastery and all new DLC, except the Peninsula Corridor shunter.
I also create three Route Guides:

Sandpatch, GWE and RT. The contents comes partly from the older version of the Starters Guide, but there also is a lot of new content in them.
I will continue working at it. The next Route Guide will be West Somerset Railway.

At steam I created a Community Guide, so you can find there as well what this all is about:

This guide does NOT contain the content, but it just gives an overview. The sole download location is not changed and will not change:
