Add capability to read custom nicknames from new thread data.

[marcel-valdez]

Fix the custom nickname functionality.

Essentially all I added was the capability to read the custom nickname data from the new thread object structure.

I also made it so that when the "use custom nickname" option is set, your user now says 'Me' instead of your actual first name and last name.

Just checked this.
Here's a couple of things though.
You don't actually need to set the nickname to "Me:" for the current user if he has a set nickname, your own nickname should be in the customization subset, this actually make everything easier.
There's also a small issue. This saves the nicknames based on individual IDs so if you have multiple nicknames in different conversations, it'll show that name in all the conversations.
Ex: Jack is name "foo" in a group chat, if you have a 1-on-1 chat with Jack it'll now show up as "foo"

You're right... and it is quite doable, I'll add the required code to show what you suggest. Just need to use a map for the nicknames where the key is the fb_id + thread_id: nickname
