Ask for confirmation when renaming a file/folder from within its properties

## Problem

At the moment there's no obvious way to cancel renaming from within the properties view. This means that (for eg.) a mis-click will rename the file/folder with no way of reverting it. Or if the user changes their mind while renaming the item, they must manually re-enter the original name which may be too long or complicated. To revert this they can first close the properties view and press ctrl+z but this isn't obvious to the user and is problematic when a file is renamed by mistake.

I personally have mistakenly pressed the ` key under Esc while closing the properties view and renamed a folder without realizing it.

## Proposal

Use an apply button to save changes instead of automatically saving them
