Add possibility to sort/filter Pokémon by different means.

[manerlan]

Ideas:

Session storage: sort alphabetically and sort by dexnumber (both ascending and descending)

Local storage: Show favorites

• Suggest to filter by pokemon type, and show the first 8 pokemon results of that type by default.
• Needs to always show the first 8 pokemon results from the api on the homepage by default.
• Alternatively: Sort alphabetically or numerically by pokedex id.

Need to add sort or filter. Can add both if we have time.
