Sort conversations by account

[trymeouteh]

Please have an account switching button and have all the conversations for one account be listed and not have all conversations from all accounts listed in the conversations list.

And then perhaps make a pull request of this feature to have it available in Conversations as well so Conversations and all forks of the Conversation app can get this highly wanted feature.

This feature is what is keeping me from getting a secondary phone number with JMP.
