[BUG] Parameters should be case insensitive

[pedwards95]

Steps to Reproduce:

1. Submit a request with capitals. eg. https://pokeapi.co/api/v2/pokemon/Iron-Crown
2. Receive no reply (404)

Requests with capitals should still work. Very easy fix just to lowercase parameters.

Hi! Could you try and implement the fix?

[pedwards95]

Yeah I can put together a PR when I get back from vacation.

Edit: This will be delayed if it comes from me.
Edit2: Update: After reviewing data during integration, and in relation to numerous asinine choice like the use of hectograms, and the refusal to fix it as seen in this ticket #1182
I will not be fixing this or any of the other issues encountered.

Fixed with #1190 and PokeAPI/deploy#50, we can close this now

Shouldn't this be closed by now? @Naramsim (don't know who else I can tag)
