Make a rule depend on rule conditions

[davidalb97]

It would be nice to have rules that depend on the enabled state of generated/defined types.

For example, using boolean conditions with the field "ruleCondition" to enable a rule configuration:

{
  "rules": [
    {
      "id": "shaders",
      "type": "DEFINED",
      "caption": "Type of optimizations: %s",
      "tooltip": "Enable Sodium optimizations (Most performant) or Optifine (Better shader tunning)?",
      "options": [
        {
          "id": "sodiumId",
          "caption": "Sodium",
          "directories": [ "modsSodium" ]
        },
        {
          "id": "optifineId",
          "caption": "Optifine",
          "directories": [ "modsOptifine" ],
          "isDefault": false
        }
      ]
    },
    {
      "id": "SodiumOnlyOptimizationsId",
      "type": "GENERATED",
      "caption": "Sodium only optimizations",
      "tooltip": "Enable other optimization mods that are not compatible with optine",
      "directories": [ "sodiumCompatibleOnlyMods" ],
      "ruleCondition": "sodiumId"
    },
    {
      "id": "SodiumOptimizationMod43AddonsId",
      "type": "GENERATED",
      "caption": "Configure mod 43's Addons",
      "tooltip": "Choose what addons are enabled for mod 43 (only compatible with Sodium)",
      "directories": [ "sodiumMod43Addons" ],
      "ruleCondition": "SodiumOnlyOptimizationsId:modid43"
    }

The first rule (DEFINED) has two options, either Sodium or Optifine.
When choosing Sodium, the user then could see a new button with sodium only mods (rule with id SodiumOnlyOptimizationsId).
When enabling a specific mod (modid43, in the example), the user could then see another button for configuring modid43's addons.

PS: Really nice work on this mod!
