Wrong Content-Type for Documents and Attachments
Microsoft Office XML Documents (and maybe more?) are sent with MIME zip instead of the correct MIME-Type.
Steps to reproduce
Try to download any .docx, .xlsx, .pptx from a repo or the wiki.
What is the current bug behavior?
The document is sent to the browser as "zip", so it cannot be opened with Word/Excel/Powerpoint.
What is the expected correct behavior?
The document ist sent with the correct MIME-Type, so the browser offers to open it with Word/Excel/Powerpoint.
