- When uploading a file, we need to flag binary files correspondingly
so that it gets propagated all the way to RepoEditor as it decides on
whether to show editor for this or that file or not (shouldHideEditor())

- rawPath needs to be propagate all the way to ContentViewer as well so
that uploaded images could be rendered as a base64 image right away
instead of raw base64 string

Merge branch 'feature/webide_escaping' of gitlab.com:hiddentiger/gitlab-ce into feature/webide_escaping

**How?**
Previously the files_decorator inserted parent folders inefficiently.
It started at the first part and ensured each was inserted.

Since the file entries are given to use in alphabetical order, we can
start at the last part of the blob's parents. If this exists, we can
short circuit and be done inserting parents.

**What else?**
- Improve performance of decorateData. The object spread operator is
not needed because the object is brand new.
