Missing apostrophes in ACP user management -> permissions

1. Go to acp.
2. Select 'users and groups' on top.
3. Select 'manage users' on the sidebar.
4. Enter 'admin'.
5. Select 'permissions' from the dropdown on the right.

Observe the following:

» Set users permissions
» Set users forum permissions

Both of those rows are missing apostrophes, probably "user's" is what was intended.
