fix(core): Fixes type caching & cleanup (#422)

- [X] Fixes some issues with the type caching
- [X] Changes type check default to ignore case
- [X] Splits out type caching of insensitive and sensitive lists. This means less stuff to iterate through when checking a type against the string.
- [X] Adds an ArrayEnumerator, mostly for reference purposes (copy/paste as needed)
