Touchscreen Buttons: Add options for floating repositioning

[ChrisNZL]

Currently in 0.3.4, button configurations are as follows:

• Movement Buttons can be repositioned, size changed, opacity changed, symbol type changed.

• Bottom Buttons (Chat, Pause, Inventory, Weapon Selector, Quick Swap) have no options.

• Combat Buttons (Jump, Shield, Attack) can have their order changed, opacity changed, icon size changed, and pivot position changed.

  • However, can't detach the three buttons from the pivot point.

• Interact and Quick Heal Buttons are fixed above the Combat Buttons without much customisation.

TODO:

• [ ] Make all buttons allowed to be circular or square, and repositionable.
• [ ] Allow shortcuts for specific weapons to be positioned anywhere on the screen.

I envision allowing the player to choose a clean slate, then adding all buttons as they see fit: circle sizes, box sizes, tap-and-drag into position.

• Probably prevent buttons from overlapping.
• Allow all buttons to be configured from a config dropdown menu.

Will require a large refactor, but keen to make it happen.

The above options will likely be turned into a Touchscreen Button Configurator (Advanced) mode.

The existing button scheme will likely be retained as Touchscreen Button Configurator (Basic).

Further idea / suggestion:

• [ ] Allow Weapon Selector UI to be positioned near its button, rather than centered over the player's character

I really can't be bothered doing this.

Will probably try this out from the get-go in the next game.

Not keen to refactor T2's mobile touchscreen button system at this point. I need to move on.
