The user can now "jump" to the webmailer and to phpmyadmin direct from within the corresponding list.

Data records are now assigned to the correct client group if they were created by the administrator.

Bug FS#267 - mail filter not hidden for client 

Fixing the way some User Interface text was used. For the quota on a mailbox I added 'in MB' so that the user knows what units the quota is in.

Now a client can view e-mail filters created by admin, but the client can't edit them. The client can submit a change, but it isn't input in the database, nor is the client told that the changes aren't made.

This is to try to fix the bug where if a filter is created by an admin, then the user with the e-mail account can't see the filter.
