Feature/updates for 200

[brunomikoski]

Changed

• Fixed issue with name parser that would still treat digits as string and add it to the final name
• Fixed issue with PropertyDrawer of indirect reference without attribute would cause a null reference
• Refactored the system to use ScriptableObject as a base class instead of ScriptableObjectCollectionItem now any ScriptableObject can be used as a collection item as long as implements the ISCOItem interface
• Fixed issue with CollectionItemPicker that would not work properly with ScriptableObject that is not in the same assembly as the ScriptableObjectCollection
• Added new buttons on CollectionRegistry to force guid validation on all items
• Reduced automatic collection guid reloading to reduce performance impact on larger projects
• Fixed issues with target scripts generation folder not being saved properly
• Minimum supported Unity version is now 2021 (I'm DONE with 2020, its the worst unity ever 😒)

Removed

• Removed support for Addressables, it was not working properly and it was not being used by a lot of teams, I think the addressables support should be handled elsewhere.

Breaking Changes

• If you used the Addressables integration SOC_ADDRESSABLES_SUPPORT be extra careful when upgrading
• The old string based guid system has been replaced for a lighter version LongGuid
• If you are using IndirectReferences all the references will be lost, you will need to re-set them

Upgrade Guide from 1.x.x to 2.x.x
