Usability: Make upload of file attaching the file as subitem

[cintek]

It seems that uploading a file via the upload button in the modify window replaces the content of the page with the content of the file.

This behaviour is confusing users because they think they upload a file as attachment of that page so they can use it on the page.

It would increase the usability if users could attach items via that button as subitems of that page and if the wiki would tell them how to embed the items on the wiki page right there.

Agree it is currently ambigious. So at a minimum "Upload file:" needs to be replaced with a more descriptive phrase while preserving the current action.

If a user wants to replace an item's content with an uploaded file, then this is only place on the current UI that does that. Clicking the current Browse button opens a dialog for a single file selection.

If we want to upload files as subitems, we probably want a multiple file selection dialog. To make it more functional, we probably want to add a rename dialog.

And then to make it more consistent, we need to add a rename function to the global Index "Browse.." button dialog.

My suggestion is to change the "Upload file" phrase to something more descriptive as a bug fix. Then add a second button to load subitems with rename functionality as an enhancement. And finally, add the rename functionality to the global Index "Browse..." dialog.
