Pipeline permissions error on new file

[kardan]

When we add a new file to be used by pipeline one need to set very loose permissions to get things to work on the vagrant box.

@danrowden mentioned maybe using a post-receive hook. Another option is to have a watcher to help out when doing work in the static dir.

The call to the old asset packer script should be removed, it's not used any longer. https://github.com/akvo/akvo-rsr/blob/develop/git_hooks/pre-commit#L13

When one runs the app we get these untracked files right now:
akvo/rsr/static/rsr/v3/js/src/react-my-details.js
akvo/rsr/static/rsr/v3/js/src/react-project-main.js
akvo/rsr/static/rsr/v3/js/src/react-user-management.js

@KasperBrandt Should we add or hide them from Git?
