Notify when my pull requests become conflicting

[mitar]

I open many pull requests against various projects. It would be great if I could be notified when any of them become conflicting with target branch so that I can fix them as soon as possible and not when maintainers of target project get ready to merge the pull request, just to discover it has conflicts.

Interesting suggestion, that seems useful, I will add it to Trello for future developments, thanks!
