This patch adds PrivilegeExecution flag to KIO jobs in dolphin thus enabling them to perform file operation with elevated privileges.
Depends on D7563 for context menu to show properly.
TODO:
- Rename action for multiple selections in a read-only folder is disabled because mass rename uses CopyJob in a loop and doing it in a read-only folder will trigger multiple prompts. Enable it again.
- Trashing from read-only folder shows error. Fix it.
