Server/Mods: Implement Mod Pack functionality

[assofohdz]

Implement a system that can load groovy mod packs (much like the dynamic loading of java classes that is in already):

https://github.com/pspeed42/moss/tree/master/action/src/main/java/com/simsilica/action https://github.com/pspeed42/moss/tree/master/mmod

See also: https://github.com/assofohdz/moss/blob/master/tools/blocked2/src/main/java/com/simsilica/blocked/ScriptState.java

and https://github.com/assofohdz/moss/tree/master/tools/mapper/sample/scripts

This is a lot of new stuff to take in, but would be very cool to have in.

• [ ] Get action and actionenvironment implemented
• [ ] Get mmod implemented
• [ ] Get ScriptState implemented and running
• [ ] How to test?
• [ ] Write a guide/doc on how to use mod packs

base-apis.json

{
    "groupId":"com.simsilica",
    "name":"base-apis",    
    "formatVersion":"1.0",
    "author":"Simsilica, LLC",
    "version":"1.0",
    dependencies: [
        "com.simsilica:base-includes"
    ],
    initScripts: [
        "base-apis.groovy"
    ],
    config: {
    }
}

modpack json file:

{
    "groupId":"com.simsilica",
    "name":"base-includes",    
    "formatVersion":"1.0",
    "author":"Simsilica, LLC",
    "version":"1.0",
    dependencies: [        
    ],
    initScripts: [
        "base-includes.groovy"
    ],
    config: {
    }
}

base-includes.groovy:

modManager.addGlobalImport("com.simsilica.action.Option");
modManager.addGlobalImport("com.simsilica.action.PromptType");
modManager.addGlobalImport("com.simsilica.mblock.*");
...

Setting up modmanager:

modManager = new ModManager();
        modManager.loadFromResource("/mythruna/base-includes.json");
        modManager.loadFromResource("/mythruna/base-apis.json");
        modManager.loadFromResource("/mythruna/base-object-api.json");
        modManager.loadFromResource("/mythruna/base-hooks-api.json");
        modManager.loadFromResource("/mythruna/base-time-api.json");
        modManager.loadFromResource("/mythruna/base-encounter-api.json");
        modManager.loadFromResource("/mythruna/objects/standard-objects.json");
        modManager.loadFromResource("/mythruna/encounters/standard-encounters.json");
        modManager.loadFromResource("/mythruna/property/base-property.json");
        modManager.loadFromResource("/mythruna/base-accounts.json");
....
        modManager.setGlobalBinding("world", world);

...then sometime later I initialize it.
