add /tiles/test route to easily reference tiles from different titles and game states

[michaeljb]

• can display a tile as it appears on the board at any given point in any given fixture

  • fixtures are processed to the specified action, and the select tiles are
    rendered; a link to the fixture at the action is rendered in the tile block

• include tiles showing the problems reported in the following issues:

  • Tile text hiding dit #4992

  • 18Ireland: IR7 and IR8 render incorrectly #5153

  • 1856: CPR Destination overlaps Green Toronto's city value #5167

  • [18Mag] Yellow O-O tiles have town name over price #5673

    • copy 18Mag fixture 76622 to a new fixture to reproduce

  • [1828.games] H22 private blocker rendering #5981

  • [1888] Mountain Tile L41 Renders Improperly #6604

  • Some problems with tile renderings #7765

  • 1830 : overlapping labels on OO tile 59 #8178

• add completed 1868 Wyoming game as a fixture

  • 1846 and 1868 Wyoming tiles added here were used for the before/after
    screenshots in [core] allow icons and upgrades to have a loc set to specify rendering location, use for DTs in 1868WY #9174

• move fixtures from /spec/fixtures/ into /public/fixtures/ so the JSON can be accessed via /fixtures/<title>/<fixture_id>.json

  • this is why there are over 200 changed files, most of them are not actually changed

• test cases defined in a location accessible by both the view code and server side code (lib/engine/test_tiles.rb) so that when the page is initially served up, it already includes the <script> tags for the games being tested

  • test cases need a title, can also have title, fixture, action, and
    any kwargs used by render_tile_blocks
