Remove "Open in file view" in Web IDE

Problem

We currently render an "Open in file view" link at the top of every file in the Web IDE. In most instances, this is the only actual content in that entire top bar, and we haven't seen much feedback about it being helpful or necessary. By removing it, we could get rid of the top bar in most cases and gain an extra 50 pixels for the actual file content.

Proposal

Original proposal

The first idea was to make the filename in the bottom bar a link.

However, as we are preparing to move more valuable information into the bottom bar, this element is one that we could potentially get rid of, so I did not want to add extra functionality to it. Instead, we could use the context menu in the filetree sidebar.

Before	After

Let's remove this link and actively listen to feedback from users whether they miss it. If that is unexpectedly the case, we can still use the idea from the original proposal.
