Change menu order for more intuitive handling

[MSindermann]

In the three-dot-menu on every video, the first menu item is currently "Edit"("Bearbeiten"), however, this does not allow users to edit the video, only the metadata. The actual menu point for editing the video is found in the middle of the drop-down list.

Proposed solutions:

• One idea is to rename the first menu item to "Edit Metadata" ("Metadaten Bearbeiten")
• Another idea is to move the menu item for opening the Video Editor to either the first or second position on the drop down list. This way, the different options of editing become more clear and the user can see and decide at one glance, which to choose.

Combining both proposed solutions might also be nice of course :)
