Blocks - implement "item # of [string] in [drop down]" reporter

Implement new reporter as per discussions with the resources team. Essentially this reporter simplifies finding the index of an item in a list by it’s value. In the event that multiple items in the list exactly match the supplied string the reporter will return the first index. In the event that no item exists that exactly matches the supplied string the reporter will return 0.

Block Spec

item # of [string] in [drop down]

Defaults

item # of [thing] in [list]

Drop-down

• [dynamic list of lists]

Position

The new reporter should be added to the data category below the item (drop down) of [drop down] reporter.

Reference

• Javascript
• Python

Since scratch generally ignores case, I’d expect this block to be completely case-insensitive. That said, it’d be really handy to have another set of blocks that can be used to test case so we could do this manually if needed

I just wondered, what about the case where you have a list containing a mixture of upper and lowercase versions of the same string. If you ask for the index of one particular string and it matches exactly to one, but only case insensitively to another, should it return the index of the exact match? or always the first matching one?
