Copy F-List Channels

Adds two line to each profile in f-list.net to copy or paste channels.

Go to the channel of one of your characters, press "Copy Channels", then go to another character and press "Paste Channels".
The second character will now have the exact same saved channel list as the first character.

Make sure to have at least one channel pinned in the new character before doing this. Doesn't matter which one, it will be replaced.
