Disable "Edit name" item for read-only items

[humdinger]

This hrev46250.

The menu item to rename a file/folder should be disabled when a read-only item is selected.

True, but somehow the end user should be notified why. A tooltip, an alert box, some "lock" icon, something. Otherwise one may think it's just broken.

[humdinger]

Maybe the disabled menu item could read "Edit name (read-only)".
A tool-tip might work.
No alerts, please. :)

The lock-icon overlay might be a bit overkill. Seeing all files and folders of a CD-ROM or a read-only mounted volume with padlocks sounds noisy. I'd reserve those for PM-related read-onlyness (see #10122), if possible.

It would be possible (and make some sense) to limit this to files that are read-only but reside on a writable disk. Maybe do that for folders only?

If our notifications were less ugly and large, one could also use them when someone tries to rename a file that cannot be renamed.

"Edit name" is still possible to click but it only allows copying the name and not actually editing it (the text area is read-only) following jscipione's changes (most recently hrev57402.)
