Grant Wizard needs an option to revoke / edit privileges

[mark-orion]

Describe the solution you'd like

The Grant Wizard is a very useful tool to add privileges for entire groups of objects (e.g. all tables). What is missing is the equivalent for revoking privileges. My suggestion: Rename the "Grant Wizard" into "Privilege Wizard" and make it more of a privilege editor that allows adding / changing and revoking privileges.
