Second attempt at an initial release. Resubmitting for approval.

Changes:

1. Removed one of the initially included mods (for performance and stability reasons).
2. Removed the included shader pack and one of the resource packs (for attribution reasons and overall simplification).
3. Updated the remaining resource pack.
4. Included a copy of the "tr7zw Protective License" for the Entity Culling mod.
5. Removed unnecessary files in the modpack.
6. Renamed the modpack to "The Cambunctious Modpack" and updated the description.

Thank you very much to the mod who caught my oversight with the shader pack attribution on my initial submission!
