BUG:358084
Change the edit profile dialog so that the profile can't be saved if:
- The profile config file is in a read-only dir (e.g. /usr/share/konsole)
- The name is empty or if the name matches the name of another already
existing profile.
If a profile gets renamed:
- Assign the same shortcut of the old profile to the newly renamed profile
- Delete the old profile (and its config file on disk). This fixes BUG:358084
Change the Manage Profiles dialog:
- The profile can only be renamed from the edit profile dialog so that we can check if the profile can be saved (from EditProfileDialog)
- Double clicking the profile name opens the edit profile dialog
