Plugin idea: Twitter lists

[dns53]

I would like a plugin that automatically follows artists as I add music to picard.
This would look for release and track artists if they have a twitter account url relationship.

Twitter supports adding followers to lists so it would be good to use this to seperate the people that you follow yourself and those automatically added by this plugin.
There is a limit of 5000 people that can be in a list, this should be enough for most people but it may be a good idea to support multiple lists if one is full.

It may be a good idea to also look at writers of works and add this to another list.
