Fixing the GU30 hotbars

[gm9]

Since I was asked about the details of my upcoming fix for the GU30 hotbar deadspace issues for use in another mod, here it is for everybody:

In the main page of your hotbars add the following

OnShow="MinimumSize='0,0'"

In the BankPage add the following:

OnHide="Parent.MinimumSize='0,0'" OnShow="Parent.MinimumSize='0,0'"

I had minimal time to test this but saw no issues. Use at your own risk.
