Simplify the upload of a container object

[George Peristerakis]

In the "Containers" panel: the user uploads an object ("upload object") to a container. The user need to fill the object name and optionally select a file. In most cases, if the user select a file, the user would enter in the object name the file name.

Suggestion:
When the file is selected and the object name field is empty, copy the filename into the object name field.

One additional suggested update to the above would be to have the file selection field first and have it automatically fill in the name. That way a user will most likely select a file first and then optionally rename it.

    Copy the selected file name in the object name field.

    In the containers panel, when uploading a object, if the user
    selects a file and the object name field is empty, copy the
    file name in the object name field. The filename string is
    saved in the file input as a attribute for comparison of any
    future changes to the file input.

    Moved the file input to improve the UX
