"continue on error" flag for pride do

[Schipy]

use case: check out branch on repos that have them

$ pride do git checkout my-branch

now it fails on first repo that doesn't have the branch
ERROR: Failed to execute "git checkout my-branch" in "/Users/Sipi/Workspace/pride-hack/boxfish-editor-loader", exit code: 1

I would like a flag that make pride ignore errors and continue with next repo
