Allow users to have multiple .pause files

I manage distributions in multiple pause accounts on a single machine. It would be nice to have local user settings for a single distribution that override global settings. I have forked and modified cpan-uploader to allow this, making the config reader prefer .pause files in the current directory. 

I'm sorry I haven't been able to test it more thoroughly, but for all my efforts, I was not able to get Dist::Zilla to install (it throws errors based on inheritance hierarchies).
