Implement GDT Custom Widget Rules

[SethDGamre]

Description

This issue replaces this: #3879

The GDT has revised the objectives for allowed and disallowed custom widgets within ranked games. Until proper modding support is implemented, the intermediate solution will be three options for lobbies to filter widgets.

• All (ideally default for unranked games, PvE and Custom)
• No Automation (default for PVP)
• None
  To be presented in a single dropdown menu where the current custom widgets modoption toggle is placed.

Why?

This is important because there are several widgets that can give orders on behalf of the player that create an unfair advantage for PvE games. Examples include auto skirmishing, automated rezbots, projectile dodging and so on. This is to serve as an intermediate solution to the inability to whitelist specific widgets in a non-bypassable way.

What area of the game does this feature request pertain?

Settings, Controls or Hotkeys

Other (optional)

The "no automation" would disable all custom widgets that issue commands using these functions: https://springrts.com/wiki/Lua_UnsyncedCtrl#Give_Order or similar until proper whitelisting support can be done.
