Changed AutoUnload to be able to manage objects generated from custom packages.

[CookStar]

This ensures the code that generates objects that expect unload in the custom packages works correctly.

# addons/source-python/packages/custom/test/__init__.py

# Source.Python Imports
#   Core
from core import AutoUnload

class Test(AutoUnload):
    def __init__(self):
        print("init Test")
    def _unload_instance(self):
        print("unloaded Test")

def test():
    return Test()

# addons/source-python/plugins/test_plugin/test_plugin.py

from test import Test
from test import test

Test()
test()

Output:

sp plugin load test_plugin
[SP] Loading plugin 'test_plugin'...
init Test
init Test
[SP] Successfully loaded plugin 'test_plugin'.
sp plugin unload test_plugin
[SP] Unloading plugin 'test_plugin'...
unloaded Test
unloaded Test
[SP] Successfully unloaded plugin 'test_plugin'.

Thank you, that works very well!
