Custom Unit Sets

[pongstylin]

Our existing apps hard-codes the set used by all teams. Create a UI that allows a user to create their own set with a similar look & feel to the original game. It will be similar, but not identical. Here are some basic requirements:

• Display the north end of the board similar to this, except there won't be a trash can, color picker, or avatar picker (MVP).
• The south end of the board where you pick your units will differ. Each available type of unit will only appear once and cannot be moved.
• Units can be placed on the board by the easiest means you can think of provided it is both mouse and touch compatible. For example, you might accomplish this by tapping a unit in the pick area to select it, then picking an empty tile. The original game used drag-n-drop, but I don't expect that to be easy.
• Units can be removed from the board by the easiest means you can think of. For example, you might accomplish this by tapping the unit twice in a row.
• There is no need to limit the number of picked units at this time. You can setup a game with 20 knights vs 20 witches if you want.

That's it! There is no need to make it possible to play with the custom set or make it possible to define the custom set for both teams. We're just going for MVP here. Just bear in mind that after it is done, we'll be looking to add these features:

• I'm hoping that the next app we create will be similar to the "Classic" app except you can define the set for both teams before beginning the game. That means the new UI will need a method to export the custom set data for game setup.
• When defining the sets for multiple player, we need to visually indicate which player is getting customized. So, for example, it might show the top half of the board first. Then, when you click a button to indicate you are done, it will switch. The bottom half of the board will appear and units are picked from above it.
• It would be nice if we could freely switch between sides. With a click of a button, you can swap between seeing the top board or the bottom board.
• It would be nice to see a preview of the full board before starting the game.

What I actually implemented differs from the requirements in a few details, but otherwise, it works. So I'm going to close this issue out. But I might change it more before I release it to the beta server at the end of the month. Here's the highlights of what is accomplished:

1. Added 2 more game types: Dropless Gray and Freestyle and you can change your default set for each one, separately. The default set is saved persistently. It will be used for all games you create and join in that style. You can also load your custom set again and change it again.
2. Drag-n-drop is supported for mouse pointers just like the old game.
3. Point-n-click is also supported as an alternative interaction style. Select a unit then select an empty tile. Works with both mice and fingers.
4. I brought back the old trash can from the original game. You can discard units with it using drag-n-drop or point-n-click.
5. I'm including the Lightning Ward unit with custom sets. It was previously implemented, but unused, so I'm going to do more testing to make sure it works well.
