Feature: Button to toggle showing advanced signal types (#9617)

The pack has become smaller over time, as most of the patches have slowly made their way into master or have been replaced with equivalent GRF files.

The patchpack currently includes the following patches:

 * Variable day length from "cargodist with sprinkles"

 * Colour code town names by company rating

 * Long char arrays for text entry boxes

The patchpack is infrequently updated to newer versions of OpenTTD.

The patchpack is designed to be compatible with online play. Anyone else who is playing will need an identical version of the patchpack, plus any used NewGRFs.

It is not possible to play with people who have a vanilla/unmodified version of OpenTTD.

Version 6.x of the patchpack is compatible with save files from:

 * Transport Tycoon (DOS version)

 * Transport Tycoon Deluxe (DOS and Windows versions)

 * TTDPatch

 * Patchpack version 5.x

 * Patchpack version 6.x (up to the version being used)

Each version of the patchpack is compiled as a Win64 binary. The binaries are placed in a Mercurial repository to make updates more convenient.

  Assuming you have not altered the binaries since last download, updates can be applied by doing "hg pull" followed by "hg update tip".

  Please be aware that if you do this, you will have no easy-update method and will need to re-download the entire pack manually on each update.
