Updating mupen64plus-qt

[Dan]

Hello,

There's a new version of mupen64plus-qt (1.12):
https://tracker.debian.org/pkg/mupen64plus-qt

This version fixes a fairly critical issue, so I'd like to get it updated in the Debian repos.

What steps would I need to take to become an uploader for this package? I already maintain cen64-qt which is nearly identical to this (https://tracker.debian.org/pkg/cen64-qt).

Thanks,
- Dan
